ARM: Tweak ECMAToInt32VFP to address regression on Nexus 4

After r13912, we saw a small regression in Kraken crypto-aes and
crypto-ccm on Nexus 4. This patch, proposed by Rodolph Perfetta,
addresses that without regressing other platforms.

Instead of looking at the exponent of double_input and trying to figure
out if the conversion will overflow, eagerly do the VCVT and return
early unless it saturated.

The mjsunit/stack-traces-overflow.js test fails on MIPS target as Error.stackTraceLimit = NaN; should disable stack trace messages and Isolate::StackOverflow() assumes static_cast<int>(double NaN) < 0.

MIPS has a different NaN representation than other architectures so the NaN value casted to int is positive. This patch adds an isnan() check to make the handling of NaN uniform on all architectures.

MIPS: ES6 symbols: Allow symbols as property names

Port r13811 (0e64f280)

Original commit message:
Since symbols and strings share a common representation, most of this change is about consistently replacing 'String' with 'Name' in all places where property names are expected. In particular, no new logic at all is necessary for maps, property dictionaries, or transitions. :) The only places where an actual case distinction is needed have to do with generated type checks, and with conversions of names to strings (especially in logger and profiler).

Left in some TODOs wrt to the API: interceptors and native getters don't accept symbols as property names yet, because that would require extending the external v8.h.

MIPS: ES6 symbols: Implement Symbol intrinsic and basic functionality

Port r13786 (b5e7a82a)

Original commit message:
- Add --harmony-symbols flag.
- Add Symbol constructor; allow symbols as (unreplaced) return value from constructors.
- Introduce %CreateSymbol and %_IsSymbol natives and respective instructions.
- Extend 'typeof' code generation to handle symbols.
- Extend CompareIC with a UNIQUE_NAMES state that (uniformly) handles internalized strings and symbols.
- Property lookup delegates to SymbolDelegate object for symbols, which only carries the toString method.
- Extend Object.prototype.toString to recognise symbols.

Per the current draft spec, symbols are actually pseudo objects that are frozen with a null prototype and only one property (toString). For simplicity, we do not treat them as proper objects for now, although typeof will return "object". Only property access works as if they were (frozen) objects (via the internal delegate object).
