Revert "Revert "Refactor HGraphBuilder and SsaBuilder to remove HLocals""
This patch merges the instruction-building phases from HGraphBuilder
and SsaBuilder into a single HInstructionBuilder class. As a result,
it is not necessary to generate HLocal, HLoadLocal and HStoreLocal
instructions any more, as the builder produces SSA form directly.
Saves 5-15% of arena-allocated memory (see bug for more data):
GMS 20.46MB => 19.26MB (-5.86%)
Maps 24.12MB => 21.47MB (-10.98%)
YouTube 28.60MB => 26.01MB (-9.05%)
This CL fixed an issue with parsing quickened instructions.

Build dominator tree before generating HInstructions
Second CL in the series of merging HGraphBuilder and SsaBuilder. This
patch refactors the builders so that dominator tree can be built
before any HInstructions are generated. This puts the SsaBuilder
removal of HLoadLocals/HStoreLocals straight after HGraphBuilder's
HInstruction generation phase. Next CL will therefore be able to
merge them.
This patch also adds util classes for iterating bytecode and switch
tables which allowed to simplify the code.

Optimizing: Do not insert suspend checks on back-edges.
Rely on HGraph::SimplifyLoop() to insert suspend checks.
CodeGenerator's CheckLoopEntriesCanBeUsedForOsr() checks the
dex pcs of suspend checks against branch targets to verify
that we always have an appropriate point for OSR transition.
However, the HSuspendChecks that were added by HGraphBuilder
to support the recently removed "baseline" interfered with
this in a specific case, namely an infinite loop where the
back-branch jumps to a nop. In that case, the HSuspendCheck
added by HGraphBuilder had a dex pc different from the block
and the branch target but its presence would stop the
HGraph::SimplifyLoop() from adding a new HSuspendCheck with
the correct dex pc.

ART: Run SsaBuilder from HGraphBuilder
First step towards merging the two passes, which will later result in
HGraphBuilder directly producing SSA form. This CL mostly just updates
tests broken by not being able to inspect the pre-SSA form.
Using HLocals outside the HGraphBuilder is now deprecated.

Create HGraph outside Builder, print timings
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.

Add loop recognition and CFG simplifications in new compiler.
We do three simplifications:
- Split critical edges, for code generation from SSA (new).
- Ensure one back edge per loop, to simplify loop recognition (new).
- Ensure only one pre header for a loop, to simplify SSA creation (existing).

Re-apply: Initial check-in of an optimizing compiler.
The classes and the names are very much inspired by V8/Dart.
It currently only supports the RETURN_VOID dex instruction,
and there is a pretty printer to check if the building of the
graph is correct.
