This patch refactors the way HGraph objects are created, moving the
instantiation out of the Builder class and creating the CodeGenerator
earlier. The patch uses this to build a single interface for printing
timings info and dumping the CFG.

This patch adds a Python script which implements a domain-specific
mini-language similar to that of LLVM's FileCheck. It is primarily
intended for writing tests for the optimizing compiler but could be
configured for other use cases too. It is implemented from scratch in
order to avoid dependency on LLVM.
Checker tests are written in Java and dex2oat is invoked with a flag
which dumps the CFG before and after each pass of the optimizing
compiler. The output is then compared against assertions in the
test's comments parsed by Checker. See comments in tools/checker.py
for more details about the currently supported language features.
This initial CL implements only one type of assertion - whether the
output contains lines matching a desired pattern in the given order -
but supports both plain text and regex matching and allows for
equivalency testing by matching for the outcome of a previous match.
See the tests in compiler/optimizing/test/ConstantFolding.java for
examples.

Currently only inlines simple things that don't require an
environment, such as:
- Returning a constant.
- Returning a parameter.
- Returning an arithmetic operation.

Move DISALLOW_COPY_AND_ASSIGN to delete functions. By no having declarations
with no definitions this prompts better warning messages so deal with these
by correcting the code.
Add a DISALLOW_ALLOCATION and use for ValueObject and mirror::Object.
Make X86 assembly operand types ValueObjects to fix compilation errors.
Tidy the use of iostream and ostream.
Avoid making cutils a dependency via mutex-inl.h for tests that link against
libart. Push tracing dependencies into appropriate files and mutex.cc.
x86 32-bit host symbols size is increased for libarttest, avoid copying this
in run-test 115 by using symlinks and remove this test's higher than normal
ulimit.
Fix the RunningOnValgrind test in RosAllocSpace to not use GetHeap as it
returns NULL when the heap is under construction by Runtime.

Don't do "if (ptr)". Use const. Use DISALLOW_COPY_AND_ASSIGN. Avoid public
member variables.
Move ValueObject to base and use in ELF builder.
Tidy VectorOutputStream to not use non-const reference arguments.

- Add art::HOptimization.
- Rename art::ConstantPropagation to art::HConstantFolding in
compiler/optimizing/constant_folding.h to avoid name
clashes with a class of the same name in
compiler/dex/post_opt_passes.h.
- Rename art::DeadCodeElimination to
art::HDeadCodeElimination for consistency reasons.
- Have art::HDeadCodeElimination and art::HConstantFolding
derive from art::HOptimization.
- Start to use these optimizations in
art:OptimizingCompiler::TryCompile.

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.

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.
