This patch makes sure, that the stack size of the new threads are never
less than PTHREAD_STACK_MIN, otherwise the pthread_attr_setstacksize()
function sets the default stack size (8MB), which leads to failure
in the BootUpMemoryUse test.

Lithium uses indexes after the maximium value ID in the HGraph as indexes
of virtual registers and assumes that the maximum value ID does not change.

The IsStandardConstant and GetConstantXX functions could add constants to
HGraph, which aliased virtual registers with real values. This could confuse
the register allocator to think that a value in a virtual register is tagged
and to incorrectly set it in the pointer map.

This is controlled by two flags:

--redirect_code_traces
--redirect_code_traces_to=<filename>

When redirection is enabled but --redirect_code_traces_to is not specified traces are written to a file code-<pid>-<isolate>.asm. This mangling scheme matches hydrogen.cfg and allows easy discovery of compilation artifacts in a multi-V8 environment (e.g. when compilation is traced from inside Chromium).

D8 defines --redirect_code_traces_to=code.asm similar to hydrogen.cfg redirection.

 - Avoid calls into ToPositiveInteger for valid cases of 'undefined' arguments.
  (Otherwise it calls into runtime).
 - Reduce the checks performed in case offset for TypedArrayFromArrayBuffer
  constructor is called with no offset argument.
