Lang Hames c35ee8b54a Use vmov.f32 to materialize f32 consts on ARM. This relaxes constraints on 
register allocation by allowing all 32 D-registers to be used. Patch by Cameron
Zwarich.

Evan Cheng 775ead3293 Fix a bad prologue / epilogue codegen bug where the compiler would emit illegal 
vpush instructions to save / restore VFP / NEON registers like this:
vpush {d8,d10,d11}
vpop {d8,d10,d11}

vpush and vpop do not allow gaps in the register list.
