Calling into JS from stack trace generation becomes an issue during
stack overflows: we'd detect a stack overflow, attempt to create an
exception, call into JS, detect a stack overflow, and repeat.

The bug occurs because we do not canonicalize character class ranges
before adding case equivalents. While adding case equivalents, we abort
early for one-byte subject strings, assuming that the ranges are sorted.
Which they are not.

In int32 multiplication, if we have a positive integer as input, then we know we can't produce a -0 answer. The same is true if truncation is applied (x * y | 0). Without this information, we have to rather annoyingly check if the result of multiplication is 0, then OR the inputs to check for negativity, and possibly return -0. In TurboFan, we'll deopt in this case.

So far TurboFan wasn't adding the deoptimization reasons for eager/soft
deoptimization exits that can be used by either the DevTools profiler or
the --trace-deopt flag. This adds basic support for deopt reasons on
Deoptimize, DeoptimizeIf and DeoptimizeUnless nodes and threads through
the reasons to the code generation.

Also moves the DeoptReason to it's own file (to resolve include cycles)
and drops unused reasons.

The GetStackPointer() routine in test-platform uses an inline
assembly code to store the current stack pointer value into a static
variable sp_addr.  The existing asm code for S390 uses an ST/STG
instruction, with the memory operand associated with the general ('=g')
constraint to sp_addr.

On GCC 4.8.5, the GCC compiler got confused and treated sp_addr as
an integer operand instead of memory operand, resulting in a store
being emitted that writes to an invalid meory location.

Given the specific store instructions being inlined here, we should
restict the sp_addr operand to explicitly be a memory operand using '=m'
instead of '=g'.

Delaying for merges caused branch cloning using dummy effect phi inputs,
potentially splitting the effect chain at start.

We still have to delay the creation for loops because we need to break

This change makes  the architecture that we target generated
v8 code for a property of the current toolchain, rather than a
global setting that applies to every toolchain.

This will allow us to properly build two snapshots for two different
architectures in a single build, which is needed for android
webview/monochrome builds.
