This patch fixes the implementation of vcvtmd_s64_f64 and vcvtpd_s64_f64
in arm_neon.h to use llfloor and llceil instead, which are ILP32-friendly.

This patch will fix the following test failure in the ILP32 mode:

FAIL: gcc.target/aarch64/vect-vcvt.c scan-assembler fcvtms\\tx[0-9]+,
d[0-9]+

OK for the trunk?
