Original Commit Message:
 .. by reusing the regexp stack from potentially multiple nested
 irregexp activations.

 To do this, we now maintain a stack pointer in RegExpStack. This stack
 pointer is synchronized at all boundaries between generated irregexp
 code and the outside world, i.e. when entering or returning from
 irregexp code, and when calling into C functions such as GrowStack.

- add a helper macro to only compare disassembled instruction (ignore

opcodes are defined in sse-instr.h, and use uppercase letters, but the

'#x in expr' currently parses incorrectly and associates #x as an
operand of an existing binary expression continuation if the previous
operator was of higher precedence. For example, 0 << #x in foo gets
incorrectly parsed as (0 << #x) in foo.

Similar optimization to the one for x64 at https://crrev.com/c/3154347.

There is a change to VisitLoad, which should call
GetEffectiveAddressMemoryOperand on the value node. This allows us to
match the input operands to the value (S128Load64Zero node), while
emitting instructions for the node (F64x2PromoteLowF32x4 node).

The CL provides a way for the embedder to hook in a special malloc-like
allocator that will be used for zone allocations.

An alternative approach would be to use weak functions with branches,
checking whether the functions were available at link-time. Those
branches could be optimized away with LTOs, so they would essentially
be free. However, the weak function approach is not portable (e.g.
there is no easy way to emulate it with msvc). The approach can be
revisited if indirect call turns out to be expensive (e.g. on hardware
with weak branch target predictors).

The CL is a prerequisite for running PCScan in the renderer process.

i32 comparisons often compare against constants, in order to implement
conditional branches. This CL optimizes such code by not loading the
constant into a register first, but directly emitting the comparison.
The code is shared for implementing {if} and {br_if} (and thereby makes
those two methods more readable).
