Hi,

aarch64_simd_const_bounds declares `lane' after an assert. This
patch moves the declaration above the assert.

This patch fixes the warning:

config/aarch64/aarch64.c: In function ‘aarch64_simd_const_bounds’:
config/aarch64/aarch64.c:6412:3: warning: ISO C90 forbids mixed declarations and code [-pedantic]

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

OK for aarch64-4.7-branch?

Thanks,
James
