c304afe54d Fix potential assertion failure in ConvertCase. 
IsOneByteRepresentationUnderneath requires the string to be flat, which is not
guaranteed in this case.  Using IsOneByteRepresentation is sufficient here.

c6841f1180 Tame mjsunit/fast-literal after fixing allocations. 
Not that allocations go through Heap::AllocateRaw and actually respect
the allocation timeout, the runtime of this test spiked. This adjusts
the limit to sane values now that the values are actually respected.

b9ce668437 Set at least PTHREAD_STACK_MIN stack size when creating threads. 
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.

bc4ad49b25 Do not add values to HGraph in Lithium. 
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.

adae3f77ec Allow redirecting disassembly and deoptimization traces into a file. 
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.
