Breaks arm64, as the method register is not correctly flagged
as ref and thus 32bit.

Also fixed some lines that were too long, and a few other minor
details.

Use method signatures, field types and types embedded in dex
insns for type inference. Perform the type inference in two
phases, first a simple pass that records all types implied
by individual insns, and then an iterative pass to propagate
those types further via phi, move, if-cc and aget/aput insns.

Bug: 17950037
This reverts commit 2535abe7d1fcdd0e6aca782b1f1932a703ed50a4.

2535abe7d1fcdd0e6aca782b1f1932a703ed50a4 17-Feb-2015 Mathieu Chartier <mathieuc@google.com> Add JIT

Currently disabled by default unless -Xjit is passed in.

The proposed JIT is a method JIT which works by utilizing interpreter
instrumentation to request compilation of hot methods async during
runtime.

JIT options:
-Xjit / -Xnojit
-Xjitcodecachesize:N
-Xjitthreshold:integervalue

The JIT has a shared copy of a compiler driver which is accessed
by worker threads to compile individual methods.

Added JIT code cache and data cache, currently sized at 2 MB
capacity by default. Most apps will only fill a small fraction of
this cache however.

Added support to the compiler for compiling interpreter quickened
byte codes.

Added test target ART_TEST_JIT=TRUE and --jit for run-test.

TODO:
Clean up code cache.
Delete compiled methods after they are added to code cache.
Add more optimizations related to runtime checks e.g. direct pointers
for invokes.
Add method recompilation.
Move instrumentation to DexFile to improve performance and reduce
memory usage.

af6925b7fe5dc5a3c8d52ee3370e86e75400f873 31-Oct-2014 Vladimir Marko <vmarko@google.com> Rewrite GVN's field id and field type handling.

Create a helper unit for dex insn classification and cache
dex field type (as encoded in the insn) in the MirFieldInfo.
Use this for cleanup and a few additional DCHECKs.

Change the GVN's field id to match the field lowering info
index (MIR::meta::{i,s}field_lowering_info), except where
multiple indexes refer to the same field and we use the
lowest of the applicable indexes. Use the MirMethodInfo from
MIRGraph to retrieve field type for GVN using this index.
This slightly reduces GVN compilation time and prepares for
further compilation time improvements.

66c6d7bdfdd535e6ecf4461bba3804f1a7794fcd 16-Oct-2014 Vladimir Marko <vmarko@google.com> Rewrite class initialization check elimination.

Split the notion of type being in dex cache away from the
class being initialized. Include static invokes in the class
initialization elimination pass.

And move the null check and class init check elimination
before the SSA transformation. The new pass ordering is in
anticipation of subsequent changes. (An improved class init
check elimination can benefit special method inlining. An
improved block combination pass before SSA transformation
can improve compilation time.)

Also add tests for the NCE.

95a059793c4c194f026afc74c713cc295d75d91a 30-May-2014 Vladimir Marko <vmarko@google.com> Global Value Numbering.

Implement the Global Value Numbering for optimization
purposes. Use it for the null check and range check
elimination as the LVN used to do.

The order of evaluation of basic blocks needs improving as
we currently fail to recognize some obviously identical
values in methods with more than one loop. (There are three
disabled tests that check this. This is just a missed
optimization, not a correctness issue.)

ScopedArenaAllocator and reuse the same variables in the
