Avoid localplt issues from x86 fereaiseexcept inline.
Building for x86_64 with float128 support, I get a localplt test failure from lrintf128 calling feraiseexcept. The problem is that an inline optimized version of feraiseexcept calls __feraiseexcept_renamed in cases where it doesn't completely expand inline, and that in turn is redirected to feraiseexcept for a library call, so meaning the redirection of feraiseexcept to __GI_feraiseexcept inside libm is lost for that call. This patch fixes the problem by moving the redirect to an internal header in the _LIBC case, with the internal header using __GI_feraiseexcept where appropriate. Tested for x86_64 (in conjunction with float128 patches). * sysdeps/x86/fpu/bits/fenv.h [_LIBC] (__feraiseexcept_renamed): Do not declare. * sysdeps/x86/fpu/include/bits/fenv.h [_LIBC && __USE_EXTERN_INLINES] (__feraiseexcept_renamed): Declare here, redirected to __GI_feraiseexcept if [SHARED && IS_IN (libm)].
