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.

Initial step towards separating IC (map check(s)), handler frontend
(prototype-check) and handler backend (actual handler code).
- Still need to split the map-check (IC) from rest of the prototype
chain check.
- Still need to turn different parts in own code objects and cache them
in more optimal places.

We were doing a redundant VCVT operation in MacroAssembler::EmitECMATruncate.
Also, setting the FPSCR exception flags is expensive on some CPUs, wo we should
try to avoid it if we can.
Thanks to Rodolph Perfetta for the input on this!

object-observe.js uses weak maps to add "hidden" properties to
objects. Previously, the hash tables it was using weren't actually
weak. This patch changes the existing runtime functions to create
instances of JSWeakMap instead of exposing ObjectHashTable directly.

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.

This fixes the following two warnings, so that "make all" builds cleanly
with Clang:

int instructions_; // Number of instructions of the expected patch size.

src/arm/simulator-arm.cc:402:20: error: variable 'words' is used uninitialized whenever 'if'
condition is false [-Werror,-Wsometimes-uninitialized]
} else if (argc == next_arg + 1) {
^~~~~~~~~~~~~~~~~~~~
../src/arm/simulator-arm.cc:407:21: note: uninitialized use occurs here
end = cur + words;
^~~~~
../src/arm/simulator-arm.cc:402:16: note: remove the 'if' if its condition is always true
} else if (argc == next_arg + 1) {

transitioned from a map with a different descriptor array (or has no back
pointer), mark all valid descriptors from the start.
This fixes the following memory leak: Map A shares a descriptor array
with map B. Map B adds constant function c that in its scope holds on to
an instance of B. If the descriptor array of A would keep all the shared
descriptors alive, including c, this keeps alive both A and c
indefinitely.
This CL also fixes a bug in descriptor array trimming. When trimming
descriptor arrays we need to trim off the slack as well (thus the entire
storage); and since we are trimming a descriptor array, we need to trim
* kDescriptorSize.

When a data property has its attributes changed but its value remains the same,
don't emit an oldValue. This makes the API more consistent by only emitting
oldValue when the value of a property has actually changed (or been removed,
in the case of a reconfiguration as an accessor property or a deletion).

Original commit message:
In preparation of supporting stubs that deopt and then need to push their
register-based parameters to an arguments area on the stack that gets properly
collected, add StubFailureTrampolineFrames to hold those parameters.
