x86: Fix UB in isinfl

Building with --enable-ubasn triggers:

$ math/test-ldouble-isinf
UBSAN: Undefined behaviour in ../sysdeps/x86/fpu/s_isinfl.c:25:8 negation of 2147483648 cannot be represented in type 'int'

Also move the isinfl implementation to sysdeps/x86 and remove the
sysdeps/x86_64 version.
