aarch64: Fix up aarch64_simd_stp<mode> [PR109977]
The aarch64_simd_stp<mode> pattern uses w constraint in one alternative and
r in another, but for the latter incorrectly uses <vw> iterator in %<vw>1 which
expands to %d1 for V2DF and %s1 for V2SF and V4SF (this one not relevant to
the pattern) and %w1 for others, so it ICEs if the alternative is selected
during final. Compared to this, <vwcore> macro has the same values for all
modes but uses w for V2DF and V2SF.

* config/aarch64/aarch64-simd.md (aarch64_simd_stp<mode>): Use <vwcore>
rather than %<vw> for alternative with r constraint on input operand.
* gcc.dg/pr109977.c: New test.
