compiler: make single Btype for methods table of identical interface type
Normally we ensure to build a single Btype for identical types.
We did not do this for methods table of identical interface
types, however. If there are two identical interface type I, I2,
they have the same Btype BI, but different Btypes for their
methods tables, BM and BM2. From the backend's point of view
only one of them is linked to BI. This can cause inconsitency
in the backend's type system, like unresolved placeholder. This
CL ensures we create a single Btype for methods table of
identical interface type.

compiler: update iota handling, fix using iota in array length
CL 71750 changed the definition of how iota works. This patch updates
gccgo for the new definition.
We've been mishandling iota appearing in a type that appears in a
const expression, as in `c = len([iota]int{})`. Correct that by copying
type expressions when we copy an expression. For simplicity only copy
when it can change the size of a type, as that is the only case where
iota in a type can affect the value of a constant (I think). This is
still a bunch of changes, but almost all boilerplate.

math: adjust compilation flags, use them when testing
We were using special compilation flags for the math package, but we
weren't using them when testing. That meant that our tests were not
checking the real code we were providing. Fix that.
Fixing that revealed that we were not using a good set of flags, or at
least were not using flags that let the tests pass. Adjust the flags
to stop using -funsafe-math-optimizations on x86. Instead always use
-ffp-contract=off -fno-math-errno -fno-trapping-math for all targets.

Use range info in split_constant_offset (PR 81635)
This patch implements the original suggestion for fixing PR 81635:
use range info in split_constant_offset to see whether a conversion
of a wrapping type can be split. The range info problem described in:
https://gcc.gnu.org/ml/gcc-patches/2017-08/msg01002.html
seems to have been fixed.
The patch is part 1. There needs to be a follow-on patch to handle:
for (unsigned int i = 0; i < n; i += 4)
{
...[i + 2]...
...[i + 3]...
which the old SCEV test handles, but which the range check doesn't.
At the moment we record that the low two bits of "i" are clear,
but we still end up with a maximum range of 0xffffffff rather than
0xfffffffc.

[AArch64] Fix SVE testsuite failures for ILP32 (PR 83846)
The SVE tests are split into code-quality compile tests and runtime
tests. A lot of the former are geared towards LP64. It would be
possible (but tedious!) to mark up every line that is expected to work
only for LP64, but I think it would be a constant source of problems.
Since the code has not been tuned for ILP32 yet, I think the best
thing is to select only the runtime tests for that combination.
They all pass on aarch64-elf and aarch64_be-elf except vec-cond-[34].c,
which are unsupported due to the lack of fenv support.
The patch also replaces uses of built-in types with stdint.h types
where possible. (This excludes tests that change the endianness,
since we can't assume that system header files work in that case.)
