Hello,
as discussed in the PR, this patch removes an invalid ENABLE_CHECKING

Tested on powerpc64-linux.
OK for mainline / 4.9 / 4.8?

The AIX ABI unfortunately does not use natural alignment. Type
double is 4 word aligned. However, the alignment of structs with a
first member of double are bumped to doubleword alignment. This
exactly conflicts with the testcase.

This fixes a few more testsuite failures on AIX. -fcompare-debug does
not work correctly on AIX and some vector tests generate extra
warnings about use of a non-standard ABI.

The patch for PR c++/58561 fixed DWARF, but did not fix Stabs
debugging. The follow patch at least stops G++ from ICE'ing for a
return type of auto. I'm not sure what type of debugging stabs should
generate, if it can represent it.
Thanks, David
