Support fields in optimizing compiler.
- Required support for temporaries, to be only used by baseline compiler.
- Also fixed a few invalid assumptions around locations and instructions
that don't need materialization. These instructions should not have an Out.

Re-enable tests with the optimizing compiler.
Tests run ok on my host/target. I reverted the move to

Make SignalTest as crashing for optimizing. We need to implement

Add some more instruction support to optimizing compiler.
This adds a few more DEX instructions to the optimizing compiler's
builder (constants, moves, if_xx, etc).
Also:
* Changes the codegen for IF_XX instructions to use a condition
rather than comparing a value against 0.
* Fixes some instructions in the ARM disassembler.
* Fixes PushList and PopList in the thumb2 assembler.
* Switches the assembler for the optimizing compiler to thumb2
rather than ARM.

Final CL to enable register allocation on x86.
This CL implements:
1) Resolution after allocation: connecting the locations
allocated to an interval within a block and between blocks.
2) Handling of fixed registers: some instructions require
inputs/output to be at a specific location, and the allocator
needs to deal with them in a special way.
3) ParallelMoveResolver::EmitNativeCode for x86.

Add a linear scan register allocator to the optimizing compiler.
This is a "by-the-book" implementation. It currently only deals
with allocating registers, with no hint optimizations.
The changes remaining to make it functional are:
- Allocate spill slots.
- Resolution and placements of Move instructions.
- Connect it to the code generator.

Give Compiler a back reference to the driver.
The compiler driver is a single object delegating work to the compiler, rather
than passing it through to every Compiler call make it a member of Compiler so
that it maybe queried. This simplifies the Compiler API and makes the
relationship to CompilerDriver more explicit.
Remove reference arguments that contravene code style.

Use trampolines for calls to helpers
This is an ARM specific optimization to the compiler
that uses trampoline islands to make calls to runtime
helper functions. The intention is to reduce the size
of the generated code (by 2 bytes per call) without
affecting performance.
By default this is on when generating an OAT file. It is
off when compiling to memory.
To switch this off in dex2oat, use the command line option:
--no-helper-trampolines
Enhances disassembler to print the trampoline entry on the
BL instruction like this:
0xb6a850c0: f7ffff9e bl -196 (0xb6a85000) ; pTestSuspend
