a7f9c491dc Use VLDR instead of VMOVs from GPR when a 64-bit double can't be encoded as a VMOV immediate. 
This requires constant blinding before it can be enabled. There are other interesting optimizations that can be added later, detailed in a TODO.

17326e8746 Refactor and improve inlined double-aligned allocations 
Change is performance neutral but generates smaller code and encapsulates double alignment in the macro-assembler rather than at the allocation site.
