Updates the Target interface, removing static from all members, so all
field accesses and member function calls go through a single global
'target'. Information relating to extern ABI are now in TargetC,
TargetCPP, and TargetObjC for each supported language respectively.

The va_list type for Alpha includes a nameless dummy field for alignment
purposes. To transpose this into D, a field named "__pad%d" is inserted
into the struct definition.
It was also noticed that in the D front-end AST copy of the backend
type, all offsets for fields generated by build_frontend_type were set
to zero due to a wrong assumption that DECL_FIELD_OFFSET would have a
non-zero value. This has been fixed to use byte_position instead.

DECL_NAME. Use byte_position to get the real field offset.

Both array concat and array new expressions wrapped any temporaries
created into a BIND_EXPR. This does not work if an expression used to
construct the result requires scope destruction, which is represented by
a TARGET_EXPR with a clean-up, and a CLEANUP_POINT_EXPR at the
location where the temporaries logically go out of scope. The reason
for this not working is because the lowering of cleanup point
expressions does not traverse inside BIND_EXPRs to expand any gimple
cleanup expressions within.
The use of creating BIND_EXPR has been removed at both locations, and
replaced with a normal temporary variable that has initialization
delayed until its address is taken.

Named arguments were being passed around by invisible reference, just
not variadic arguments. There is a need to de-duplicate the routines
that handle declaration/parameter promotion and reference checking.
However for now, the parameter helper functions have just been renamed
to parameter_reference_p and parameter_type, to make it more clear that
it is the Parameter equivalent to declaration_reference_p and
declaration_type.
On writing the tests, a forward-reference bug was discovered on x86_64
during va_list type semantic. This was due to fields not having their
parent set-up correctly.

Pragma inline affects whether functions are inlined or not. If at the

* New core.math.toPrec templates have been added as an intrinsic.
Some floating point algorithms, such as Kahan-Babuska-Neumaier
Summation, require rounding to specific precisions. Rounding to
precision after every operation, however, loses overall precision in
the general case and is a runtime performance problem.
Adding these functions guarantee the rounding at required points in
the code, and document where in the algorithm the requirement exists.

This patch addresses two problems with TypeInfo initializer generation.
1. D array fields pointing to compiler generated data are referencing
public symbols with no unique prefix, which can lead to duplicate
definition errors in some hard to reduce cases. To avoid name clashes,
all symbols that are generated for TypeInfo initializers now use the
assembler name of the TypeInfo decl as a prefix.
2. An ICE would occur during LTO pass because these same decls are
considered to be part of the same comdat group as the TypeInfo decl that
it's referred by, despite itself being neither marked public nor comdat.
This resulted in decls being added to the LTRANS partition out of order,
triggering an assert when add_symbol_to_partition_1 attempted to add
them again. To remedy, TREE_PUBLIC and DECL_COMDAT are now set on all
generated symbols.

1. Implement DIP 1010 - (Static foreach)
Support for 'static foreach' has been added. 'static foreach' is a conditional
compilation construct that is to 'foreach' what 'static if' is to 'if'. It is
a convenient way to generate declarations and statements by iteration.
import std.conv: to;
static foreach(i; 0 .. 10)
{
// a 'static foreach' body does not introduce a nested scope
// (similar to 'static if').
// The following mixin declaration is at module scope:
// declares 10 variables x0, x1, ..., x9
mixin('enum x' ~ to!string(i) ~ ' = i;');
}
import std.range: iota;
// all aggregate types that can be iterated with a standard 'foreach'
// loop are also supported by static foreach:
static foreach(i; iota(10))
{
// we access the declarations generated in the first 'static foreach'
pragma(msg, "x", i, ": ", mixin(`x` ~ to!string(i)));
static assert(mixin(`x` ~ to!string(i)) == i);
}
void main()
{
import std.conv: text;
import std.typecons: tuple;
import std.algorithm: map;
import std.stdio: writeln;
// 'static foreach' has both declaration and statement forms
// (similar to 'static if').
static foreach(x; iota(3).map!(i => tuple(text("x", i), i)))
{
// generates three local variables x0, x1 and x2.
mixin(text(`int `,x[0],` = x[1];`));
scope(exit) // this is within the scope of 'main'
{
writeln(mixin(x[0]));
}
}
writeln(x0," ",x1," ",x2); // first runtime output
}
2. Aliases can be created directly from a '__trait'.
Aliases can be created directly from the traits that return symbol(s) or
tuples. This includes 'getMember', 'allMembers', 'derivedMembers', 'parent',
'getOverloads', 'getVirtualFunctions', 'getVirtualMethods', 'getUnitTests',
'getAttributes' and finally 'getAliasThis'. Previously an 'AliasSeq' was
necessary in order to alias their return. Now the grammar allows to write
shorter declarations:
struct Foo
{
static int a;
}
alias oldWay = AliasSeq!(__traits(getMember, Foo, "a"))[0];
alias newWay = __traits(getMember, Foo, "a");
To permit this it was more interesting to include '__trait' in the basic types
rather than just changing the alias syntax. So additionally, wherever a type
appears a '__trait' can be used, for example in a variable declaration:
struct Foo { static struct Bar {} }
const(__traits(getMember, Foo, "Bar")) fooBar;
static assert(is(typeof(fooBar) == const(Foo.Bar)));
3. fix Issue 10100 - Identifiers with double underscores and allMembers
The identifer whitelist has been converted into a blacklist of all possible
internal D language declarations.

build_same_sized_truth_vector_type was confusingly named, since for
SVE and AVX512 the returned vector isn't the same byte size (although
it does have the same number of elements). What it really returns
is the "truth" vector type for a given data vector type.
The more general truth_type_for provides the same thing when passed
a vector and IMO has a more descriptive name, so this patch replaces
all uses of build_same_sized_truth_vector_type with that. It does
the same for a call to build_truth_vector_type, leaving truth_type_for
itself as the only remaining caller.
It's then more natural to pass build_truth_vector_type the original
vector type rather than its size and nunits, especially since the
given size isn't the size of the returned vector. This in turn allows
a future patch to simplify the interface of get_mask_mode. Doing this
also fixes a bug in which truth_type_for would pass a size of zero for
BLKmode vector types.

C2x adds <float.h> constants FLT_NORM_MAX, DBL_NORM_MAX and
LDBL_NORM_MAX. These are for the maximum "normalized" finite
floating-point number, where the given definition of normalized is
that all possible values with MANT_DIG significand digits (leading one
not zero) can be represented with that exponent. The effect of that
definition is that these macros are the same as the corresponding MAX
macros for all formats except IBM long double, where the NORM_MAX
value has exponent 1 smaller than the MAX one so that all 106 digits
can be 1.
This patch adds those macros to GCC. They are only defined for float,
double and long double; C2x does not include such macros for DFP
types, and while the integration of TS 18661-3 into C2x has not yet
occurred, the draft proposed text does not add them for the _FloatN /
_FloatNx types (where they would always be the same as the MAX
macros).
Bootstrapped with no regressions on x86_64-pc-linux-gnu. Also tested
compilation of the new test for powerpc-linux-gnu to confirm the check
of LDBL_NORM_MAX in the IBM long double case does get properly
optimized out.

The SVE port now tries to register variable-length VECTOR_TYPEs
at start-up, so it's no longer possible to use the asserting
to_constant on the number of vector elements. This patch punts
on variable element counts instead, just like we do for other
things that the frontend doesn't recognise.
The brace indentation matches the surrounding style.
