The wide_int routines allow things like:
wi::add (t, 1)
to add 1 to an INTEGER_CST T in its native precision. But we also have:
wi::to_offset (t) // Treat T as an offset_int
wi::to_widest (t) // Treat T as a widest_int
Recently we also gained:
wi::to_wide (t, prec) // Treat T as a wide_int in preccision PREC
This patch therefore requires:
wi::to_wide (t)
when operating on INTEGER_CSTs in their native precision. This is
just as efficient, and makes it clearer that a deliberate choice is
being made to treat the tree as a wide_int in its native precision.
This also removes the inconsistency that
a) INTEGER_CSTs in their native precision can be used without an accessor
but must use wi:: functions instead of C++ operators
b) the other forms need an explicit accessor but the result can be used
with C++ operators.
It also helps with SVE, where there's the additional possibility
that the tree could be a runtime value.

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 means that we know when accessing the modes that the size is
a compile-time constant, even for SVE. It also enables stricter
type safety in later patches.

This patch adds a macro that extracts the TYPE_MODE and forcibly
converts it to a scalar_float_mode. The forcible conversion
includes a gcc_checking_assert that the mode is a SCALAR_FLOAT_MODE_P.
This becomes important as more static type checking is added by
later patches. It has the additional benefit of bypassing the
VECTOR_TYPE_P (...) ? vector_type_mode (...) : ... condition
in TYPE_MODE; in release builds the new macro is a simple
field access.

This patch makes various changes that allow modes like SImode to be
classes rather than enums.
Firstly, it adds inline functions for all mode size properties,
with the macros being simple wrappers around them. This is necessary
for the __builtin_constant_p trick to continue working effectively when
the mode arguments are slightly more complex (but still foldable at
compile time).
These inline functions are trivial and heavily used. There's not much
point keeping them out-of-line at -O0: if anything it would make
debugging harder rather than easier, and it would also slow things down.
The patch therefore marks them as "always_inline", if that's available.
Later patches use this approach too.
Using inline functions means that it's no longer possible to pass
an int to GET_MODE_PRECISION etc. The Fortran and powerpcspe-c.c
parts are needed to avoid instances of that.
The patch continues to use enums for gencondmd.c, so that more
mode comparisons are integer constant expressions when checking
for always-true or always-false conditions. This is the only
intended use of USE_ENUM_MODES.
The patch also enforces the previous replacement of case statements
by defining modes as:
#define FOOmode ((void) 0, E_FOOmode)
This adds no overhead but makes sure that new uses of "case FOOmode:"
don't accidentally creep in when FOOmode has no specific class associated
with it.
