c/68162).
PR c/68162 reports a spurious warning about incompatible types
involving arrays of const double, constructed in one place using a
typedef for const double and in another place literally using const
double.
The problem is that the array of the typedef was incorrectly
constructed without a TYPE_MAIN_VARIANT being an array of unqualified
elements as it should be (though it seems some more recent change
resulted in this producing incorrect diagnostics, likely the support
for C++-style handling of arrays of qualified type). This patch fixes
the logic in grokdeclarator to determine first_non_attr_kind, which is
used to determine whether it is necessary to use the TYPE_MAIN_VARIANT
of the type in the declaration specifiers.
However, fixing that logic introduces a failure of
gcc.dg/debug/dwarf2/pr47939-4.c, a test introduced along with
first_non_attr_kind. Thus, it is necessary to track the original
qualified typedef when qualifying an array type, to use it rather than
a newly-constructed type, to avoid regressing regarding typedef names
in debug info. This is done along lines I suggested in
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47939#c6>: track the
original type and the number of levels of array indirection at which
it appears, and, in possibly affected cases, pass extra arguments to
c_build_qualified_type (with default arguments to avoid needing to
pass those extra arguments explicitly everywhere). Given Richard's
recent fix to dwarf2out.c, this allows the C bug to be fixed without
causing debug information regressions.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

While enabling graphite in -O3 we found a Fortran testcase that fails
because the max of the type domain is -1. We used to add that as a constraint
to the elements accessed by the array, leading to a unfeasible constraint:
0 <= i <= -1. Having that constraint, drops the data reference as that says
that there are no elements accessed in the array.

On 64-bit we can do comparisons of 32-bit values by extending those
values to 64-bit, subtracting them, and then getting the high bit of
the result. For registers this is always cheaper than using the carry
bit sequence; and if the comparison involves a constant, this is cheaper
than the sequence we previously generated in half of the cases (and the
same cost in the other cases).
After this, the only sequence left that is using the mfcr insn is the
one doing signed comparison of Pmode registers.

The problem in the PR is that some i386 optabs FAIL when
optimising for size rather than speed. The gimple level generally
needs access to this information before calling the generator,
so this patch adds a new hook to say whether an optab should
be used when optimising for size or speed. It also has a "both"
option for cases where we want code that is optimised for both
size and speed.
I've passed the optab to the target hook because I think in most
cases that's more useful than the instruction code. We could pass
both if there's a use for it though.
At the moment the match-and-simplify code doesn't have direct access
to the target block, so for now I've used "both" there.
Tested on x86_64-linux-gnu and powerpc64-linux-gnu.
