Previously, the Intl.DateTimeFormat constructor and other related paths had
a bug where the options bag passed in would be modified in place. This patch
makes V8's Intl implementation follow the specification's logic to avoid
such a modification.

Use FastAsciiConvert (as used by Unibrow) for i18n-aware
case conversion with --icu_case_mapping.
Move FastAsciiConvert to src/string-case.cc so that it can be used
by both runtime-{string,i18n}.
Add more tests.

This CL implements GetPossibleBreakpoints for wasm, by iterating over
all functions in the requested range and returning the location of all
instructions within that range.
The connection to the inspector will be added later, when setting
breakpoint also works for wasm: http://crrev.com/2536763002

When executing wasm code for testing, we did not create a
WasmInstanceObject and link it to the generated code. This required
some special handling at runtime (mainly for stack trace generation).
This CL always provides the WasmInstanceObject, such that e.g. function
names can be resolved the usual way.
The module bytes referenced by the WasmCompiledModule linked with the
WasmInstanceObject do not hold a valid wasm module yet. Instead, we
just add the bytes we need, and make the objects in WasmModule point to
those bytes (currently only used for function names). Those bytes will
not be parsed at runtime anyway.

The scenario here: the asm function fails asm validation,
so we emit a message. In doing so, we create a JSValue wrapper for
the script object that we cache on the script object. This wrapper
is context-dependent and causes the code serializer to choke.

The inspector cannot deal with breaking inside of debug-evaluate.
There is therefore no point in supporting that in the debugger.
The optional additional context parameter for debug-evaluate also
can be removed since it's not being used.

Reason for revert:
This change rendered InstructionSequenceTest::SetNumRegs ineffectual, thus
loosening the tests that were using that API to ensure correct register
allocation under intentionally constrained setups.
For the problem stated in this CL, a solution needs to continue supporting the
intentionally set-up test configuration.
Original issue's description:
> MIPS: Fix bad RegisterConfiguration usage in InstructionSequence unit tests.
>
> Test InstructionSequenceTest has been initialized with a testing RegisterConfiguration
> instance defined in instruction-sequence-unittest.h, whereas class ExplicitOperand which
> is being tested used RegisterConfiguration from instruction.cc. In case these two
> instances are different, the tests would fail. The issue is fixed by using the same
> instance of RegisterConfiguration both for test code and code under test.
>
> Additionally, the tests in register-allocator-unittest.cc use hardcoded values
> for register and begin failing is the hardcoded register is not available for
> allocation. Fix by forcing the use of allocatable registers only.

Transform LdaNull/LdaUndefined followed by StrictEquality to TestNull/TestUndefined.
This would avoid a call to the compare IC. In the bytecode-graph builder these are
mapped to StrictEqual javascript operator. When reducing this operator, we already
optimize the cases for null/undefined.

If a context snapshot includes the global proxy constructor function, we
expect the incoming global proxy to have the correct instance size so
that we can reinitialize it with said constructor. However, when the
bootstrapper allocates a new global proxy, we need to know the expected
size.
We solve this by storing the size on the to-be-serialized isolate.

This introduces an explicit struct for the communication channel between
the {ArrayLiteral} AST node and the corresponding runtime methods. Those
methods take a pair of {ElementsKind} as well as an array (can either be
a FixedArray or a FixedDoubleArray) of constant values.
For bonus points it also reduces the size of the involved heap object by
one word (i.e. length field of FixedArray not needed anymore).

The WasmRunner now always holds a TestingModule, and allows to add
several functions to it. The prepares a change to always run wasm code
with a full module behind it, removing the special handling for "no wasm
instance" at runtime (http://crrev.com/2551053002).
This CL here also templatizes the WasmRunner such that the Call method must
be called with the same signature specified for the WasmRunner. This
already catched several mismatches there.
