[PATCH] [X86][FastIsel] Teach how to select vector load instructions.

[Andrea Di Biagio]

Hi qcolombet, ributzka, mkuper,

This patch teaches fast-isel how to select 128-bit vector load instructions.

I simply extended the switch statement in method 'X86FastEmitLoad' adding extra cases for 128-bit vector types.
I had to slightly modify the signature of 'X86FastEmitLoad' to allow selecting opcodes based on alignment information.

Added test CodeGen/X86/fast-isel-vecload.ll

Please let me know if ok to submit.

Thanks,
Andrea
