the only platform that it works on is linux (using the prctl API to set the
names of the threads). Other platforms are setup to build properly if the
flag is set, but their thread names are not currently set.

The function HEnvironment::SetExpressionStackAt did not update the
environment's history.  This function is used to patch the bailout
environment for count operations and global function calls.

Reorganize class HEnvironment to make it fit V8's style a bit better
and to try to add some sanity to which C++ functions are intended to
be inlined.

Remove the flag --trace-environment which merely duplicated data in
the hydrogen.cfg file except without enough context to be useful.

1. Separating out the instance-type check from the array-length operation.

2. I also changed the bounds-check on keyed loads to use the length property
for JS arrays (like we do for array stores).

The new pattern should use less registers and allow more checks to be eliminated.

Array.slice doesn't mutate original array, so it's fine with read only data.

The assumption is that most utf8 strings allocated are actually ascii
and that if they are not we will encounter a non-ascii char pretty
quickly.

The Hydrogen environment only tracks values for stack-allocated variables.
It is a precondition of HEnvironment::Lookup(variable) that variable is
stack-allocated.  The check was missing at one call site.

Ensure that the SSE2 TranscendentalCache stub calls GC if it runs out of memory in new space.  Previously, it would just use an alternate algorithm, that did not cache the result.
