In aarch64_float_const_representable, `sign' is unused.

This patch removes all references to it. The patch is equally
applicable to trunk and aarch64-4.7-branch.

This patch fixes the warning:

config/aarch64/aarch64.c: In function ‘aarch64_float_const_representable_p’:
config/aarch64/aarch64.c:7075:7: warning: variable ‘sign’ set but not used [-Wunused-but-set-variable]

Regression tested on aarch64-none-elf with no regressions.

OK for trunk and aarch64-4.7-branch?
