ARM: Make DoStoreKeyedFixedDoubleArray faster; don't allow conditional Vmov

This patch makes us generate faster code for DoStoreKeyedFixedDoubleArray,
by using a branch rather than a conditional Vmov instruction.

Conditional VFP instructions are not a great idea in general, and it was
especially bad in this case because Vmov expands to a bunch of instructions.
For this reason, the patch also removes the 'cond' parameter from Vmov.

Thanks to Rodolph for pointing me to this!

ARM: Change signature for vmov.32 function in the assembler

The assembler has 8 different vmov variants. The one for vmov.32 and for moving
an immediate into a double reg only differs in the type of the second
paremeter: vmov.32 takes an int, the other takes a double.

The situation is dangerous because C++ will happily implicitly convert between
int and double.

This patch changes the signature of the vmov.32 assembler function so that it
cannot be confused with the other vmovs.

Port r13585 (4174b9d2)

Original commit message:
This includes:
* Adding support for saving callee-clobbered double registers in Crankshaft code.
* Adding a new "HTrapAllocationMemento" hydrogen instruction to handle AllocationSiteInfo data in crankshafted stubs.
* Adding a new "HAllocate" hydrogen instruction that can allocate raw memory from the GC in crankshafted code.
* Support for manipulation of the hole in HChange instructions for Crankshafted stubs.
* Utility routines to manually build loops and if statements containing hydrogen code.

Simplify secure API functions workaround for MinGW

If MINGW_HAS_SECURE_API is defined, the definitions of localtime_s,
fopen_s, _vsnprintf_s, strncpy_s had to be renamed using #define
so they would not conflict with definitions in the standard headers.

A simpler way to handle this is to undefine MINGW_HAS_SECURE_API before
including the standard headers.
