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.

6a4e239773 Create a sparate pass to remove unreachableble CFG blocks. 
SCCP pass removes unreachable blocks before CFG construction.
In case of -O0 or -O1 pipeline (without SCCP) it's simpler and faster
to unlink unreachable CFG blocks once, then check for reachability
in almost any compilation pass.
-O2 pipeline (with SCCP) don't need this pass.
