Testcase

This might be a dup of PR52372 or PR57933 but since I am not sure I am opening
a new bug.

When trying to compile powerpc libgcc fp-bit I get an ICE using trunk:

I will attach the fp-bit.i reduced version.

--- Comment #11 from Jacob Abel <thatcadguy at gmail dot com> ---
The culprit that -march=native activates on my Core i7 laptop is -mavx.
Compiling with -mavx causes the segfault, without is fine. Unfortunately, that
flag was not set on my other laptop, so might be multiple issues here.
