This patch removes the %e error for AIX, since it seems there has been
no attempt to keep cpu support up to date for AIX, and adds missing
entries to ASM_CPU_SPEC in rs6000.h. The rs64a->rs64 name change
happened a long time ago as a fix for PR20813 (git commit c92b4c3f5b).

The c-c++-common tests fail (or XPASS depending on which) on Darwin
because it doesn't currently emit .ident marker. For X86 Darwin, this

During 8.x, the rs6000 target-specific mangling was reorganised which uncovered
a long-standing bug in Darwin’s mangling for ‘IBM’ long double. Now the symbols
are correctly mangled, and we end up with a bunch of test link fails.
This patch adds the necessary subset of the Linux long double exports to Darwin’s
export table.

On some version of dejagnu, options in RUNTESTFLAGS are appended to the
command-line and thus any -mfloat-abi=softfp or -mfloat-abi=hard in
there overwrite the -mfloat-abi=soft in the dg-options for
size-optimization-ieee-* tests. Test is still run though because
arm_soft_ok returns true if -mfloat-abi=soft is accepted, even if the
file is not compiled for softfloat due to a later -mfloat-abi on the
command line.
This patch adds a dg-skip-if to those tests to ensure they are not run
in softfp or hard mode.
