239f981653 MIPS: [stubs,interpreter] Optimise SMI loading for 64-bit targets.
Port 28e3467a72 (r38361)

  original commit message:
    Adding new methods to the code stub assembler and interpreter
    assembler to combine loading and untagging SMIs, so that on 64-bit
    architectures we can avoid loading the full 64 bits and load the
    32 interesting bits directly instead.

ba092fb09a [turbofan] Change Float64Max/Float64Min to JavaScript semantics.
So far we don't have a useful way to inline Math.max or Math.min in
TurboFan optimized code. This adds new operators NumberMax and NumberMin
and changes the Float64Max/Float64Min operators to have JavaScript
semantics instead of the C++ semantics that it had previously.

This also removes support for recognizing the tenary case in the
CommonOperatorReducer, since that doesn't seem to have any positive
impact (and actually doesn't show up in regular JavaScript, where
people use Math.max/Math.min instead).

Drive-by-fix: Also nuke the unused Float32Max/Float32Min operators.

edf8c03547 MIPS64: Implement Mips64And32, Mips64Or32, Mips64Nor32 and Mips64Xor32 operators.
If operands are loaded as unsigned 32-bit integer, they need to be sign extended to 64 bits.

bb2a830deb [turbofan] Make MachineType a pair of enums.
MachineType is now a class with two enum fields:
- MachineRepresentation
- MachineSemantic

Both enums are usable on their own, and this change switches some places from using MachineType to use just MachineRepresentation. Most notably:
- register allocator now uses just the representation.
- Phi and Select nodes only refer to representations.

c0c214daa8 [Interpreter] Add support for loading from / storing to outer context variables.
Adds support for loading from and storing to outer context
variables. Also adds support for declaring functions on contexts and
locals. Finally, fixes a couple of issues with StaContextSlot where
we weren't emitting the write barrier and therefore would crash in the
GC.

Also added code so that --print-bytecode will output the
function name before the bytecodes, and replaces MachineType with StoreRepresentation in RawMachineAssembler::Store and updates tests.

8c3af6ca03 MIPS: [turbofan] Add new Float32Abs and Float64Abs operators.
Port 9af9f1d026

Original commit message:
These operators compute the absolute floating point value of some
arbitrary input, and are implemented without any branches (i.e. using
vabs on arm, and andps/andpd on x86).

The CL enables the same instructions are selected for Word32 and Word64 compare
