Relax representation requirement in FrameStates.
...
This change enables non-tagged representations in FrameStates.
That allows us to run zlib with deoptimization support and have almost the same performance of the generated code (as the code with no deoptimization). Unfortunately, the frame states seem to confuse typer. As a consequence, we generate more representation changes, which in turn causes the scheduler to take a lot more time and memory (>4x). The added compiler time makes zlib with deopt be about 50% slower.

The StaticParameterTraits are broken by design, and cause way too much
trouble. The compilers usually pick the wrong specialization (i.e. the
default specialization is picked for Load and Phi even tho there is a
specialization for MachineType), which is not only the reason why GVN is
ineffective and slow, but can also lead to correctness issues in some
rare cases.
Also clean up some minor bugs/inconsistencies on the way.

directly pushed to git.

Clean up manual bit field usage in PreParserExpression
...
Instead of using an integer value and manual bit-fiddling, use C++'s
support for specifying bit sizes for integral types. This way the bits
used to describe a PreParserExpression are handled by the compiler.

Further improve hashing of pointers and integers.
...
Also make sure that the appropriate functions are inlined properly
(using V8_INLINE instead of inline to enforce it even with GCC),
and improve the HashIsOkish unittest.

[turbofan] Fix lowering of typed loads/stores.
...
Only JSLoadProperty/JSStoreProperty nodes with external typed arrays can
be lowered to LoadElement/StoreElement, because lowering of non-external
typed arrays would require a map check.

Remove extraneous line from CompareWrapper test
...
On platforms without TurboFan (PowerPC) the CompareWrapper test was
failing. It appears the line
RawMachineAssemblerTester<int32_t> m;
was causing the issue, and does not appear to be required for the
test to operate correctly. Removing it resolves the crash on non
TurboFan platforms
