This patch replaces the REDUC_*_EXPR tree codes with internal functions.
This is needed so that the upcoming in-order reductions can also use
internal functions without too much complication.

I took the documentation of the FRAME_GROWS_DOWNWARD behaviour from the
version that was in most header files, since the one in the manual seemed
less clear.
The patch deliberately keeps FIRST_PARM_OFFSET(FNDECL) in
microblaze_starting_frame_offset; this seems to be a port-local
convention and takes advantage of the fact that FIRST_PARM_OFFSET
doesn't read FNDECL.

This patch is like the earlier GET_MODE_UNIT_SIZE one,
but for precisions rather than sizes. There is one behavioural
change in expand_debug_expr: we shouldn't use lowpart subregs
for non-scalar truncations, since that would just reinterpret
some of the scalars and drop the rest. (This probably doesn't
trigger in practice.) Using TRUNCATE is fine for scalars,
since simplify_gen_unary knows when a subreg can be used.

A proposal is to introduce a target independent flag
-fcf-protection=[none|branch|return|full] with a semantic to
instrument a code to control validness or integrity of control-flow
transfers using jump and call instructions. The main goal is to detect
and block a possible malware execution through transfer the execution
to unknown target address. Implementation could be either software or
target based. Any target platforms can provide their implementation
for instrumentation under this option.
The compiler should instrument any control-flow transfer points in a
program (ex. call/jmp/ret) as well as any landing pads, which are
targets of control-flow transfers.
A new 'nocf_check' attribute is introduced to provide hand tuning
support. The attribute directs the compiler to skip a call to a
function and a function's landing pad from instrumentation. The
attribute can be used for function and pointer to function types,
otherwise it will be ignored.
Currently all platforms except i386 will report the error and do no
instrumentation. i386 will provide the implementation based on a
specification published by Intel for a new technology called
Control-flow Enforcement Technology (CET).

Previously VECTOR_CST_NELTS (t) read the number of elements from
TYPE_VECTOR_SUBPARTS (TREE_TYPE (t)). There were two ways of handling
this with variable TYPE_VECTOR_SUBPARTS: either forcibly convert the
number to a constant (which is doable) or store the number directly
in the VECTOR_CST. The latter seemed better, since it involves less
pointer chasing and since the tree_node u field is otherwise unused
for VECTOR_CST. It would still be easy to switch to the former in
future if we need to free up the field for someting else.
The patch also changes various bits of VECTOR_CST code to use
VECTOR_CST_NELTS instead of TYPE_VECTOR_SUBPARTS when iterating
over VECTOR_CST_ELTs. Also, when the two are checked for equality,
the patch prefers to read VECTOR_CST_NELTS (which must be constant)
and check against TYPE_VECTOR_SUBPARTS, instead of the other way
around.

PR82045 is about a bootstrap failure on sparc-sun-solaris2.11.
The problem was that we were passing the new machine_mode wrapper
classes through "..." to emit_library_call(_value), which then
read them back as ints instead.
The simplest fix seemed to be replace "..." with an array of
rtx_mode_ts, then provide wrappers for the common cases. This
bulks out rtl.h a bit, but it does make things a bit more typesafe.

This patch adds a scalar_mode class that can hold any scalar mode,
specifically:
- scalar integers
- scalar floating-point values
- scalar fractional modes
- scalar accumulator modes
- pointer bounds modes

Later patches add more uses.

This patch adds asserting as_a <scalar_int_mode> conversions
to contexts in which the input is known to be a scalar integer mode.
In expand_divmod, op1 is always a scalar_int_mode if
op1_is_constant (but might not be otherwise).
In expand_binop, the patch reverses a < comparison in order to
avoid splitting a long line.

This patch replaces checks of "SCALAR_INT_MODE_P (...)" with
"is_a <scalar_int_mode> (..., &var)" in cases where it becomes
useful to refer to the mode as a scalar_int_mode. It also
replaces some checks for the two constituent classes (MODE_INT
and MODE_PARTIAL_INT).
The patch also introduces is_a <scalar_int_mode> checks for some
uses of HWI_COMPUTABLE_MODE_P, which is a subcondition of
SCALAR_INT_MODE_P.

This patch adds a wrapper around smallest_mode_for_size
for cases in which the mode class is MODE_INT. Unlike
(int_)mode_for_size, smallest_mode_for_size always returns
a mode of the specified class, asserting if no such mode exists.
smallest_int_mode_for_size therefore returns a scalar_int_mode
rather than an opt_scalar_int_mode.

A debug insn after the final jump of a basic block may cause the
expander to emit a dummy move where the non-debug compile won't
because it finds the jump insn at the end of the insn stream.
Fix the condition so that, instead of requiring the jump as the last
insn, it also matches a jump followed by debug insns.
This fixes the compilation of libgcc/libgcov-profiler.c with
-fcompare-debug on i686-linux-gnu.

* cfgexpand.c (expand_gimple_basic_block): Disregard debug
insns after final jump in test to emit dummy move.

While changing LABEL_REF_LABEL it might as well become an inline
function, so that its clearer what types are involved. Unfortunately
because it is still possible to use XEXP and related macros on a
LABEL_REF rtx you can still set the field to be a non insn rtx. The
other unfortunate thing is that the generators actually create LABEL_REF
rtx that refer to MATCH_x rtx, so there we actually need to use XEXP to
bypass the checking this patch adds.
