24f58e7759 Comment assertion to allow PHP/JIT/Win64 work 
Win64 calling convention defines volatile FP registers.
PHP JIT for Win64 saves and restores only GP registers.
This potentionaly may cause register clobbering and unexpected behavior.

e2810c070e Save and restore used non-volatile XMM registers in prologue and epilogue. 
We currently save only "single double" part of the registers using
"movsd" instruction. In general, we should save and restore the whole XMM
registers.
