Require linker plugin for pr78768.c

The test-case has an xfail-ed line.  For linkers without plugin support, that
line happens to xpass.  Require linker with plugin support, such that the line
is no longer xpass-ing, but unsupported.

sense. Is_Exception_Safe was missing various cases -- calls inside
a pragma Debug, calls inside an 'if' or assignment statement,

in instances are not rechecked in Valid_Conversion because
visibility changes between generic location andi instance may

[AArch64] Fix for gcc-7 regression PR 80530

This patch fixes the regression caused by the changes to add square root
estimation when compiling for xgene-1 or exynos-m1 targets.

The issue is that the expand path for the reciprocal estimate square
root pattern assumes that pattern cannot fail once it has been decided
that this expansion path is available, but because the logic deep inside
aarch64_emit_approx_sqrt() differs from use_rsqrt_p() the two disagree
as to what is safe.

This patch refactors the logic to ensure that we cannot unknowingly make
different choices here.

PR target/80530
* config/aarch64/aarch64.c (aarch64_emit_approx_sqrt): Ensure
that the logic for permitting reciprocal estimates matches that
