This reverts commit 61908880e6565acfadbafe93fa64de000014f1a6.
Reason for revert: By failing to round multiply results, it does not follow Java rounding rules.

Rationale:
The change introduces actual conditional passes
(dependence on inliner). This ensures more
cases are optimized downstream without
needlessly introducing compile-time.
NOTE:
Some checker tests needed to be rewritten
due to subtle changes in the phase ordering.
No optimizations were harmed in the process,
though.

Make code item fields private and use accessors. Added a hand full of
friend classes to reduce the size of the change.
Changed default to be nullable and removed CreateNullable.
CreateNullable was a bad API since it defaulted to the unsafe, may
add a CreateNonNullable if it's important for performance.
Motivation:
Have a different layout for code items in cdex.

This helps save memory by avoiding the allocation of
HEnvironment and related objects for AOT references to
boot image strings and classes (kBootImage* load kinds)
and also for JIT references (kJitTableAddress).
Compiling aosp_taimen-userdebug boot image, the most memory
hungry method BatteryStats.dumpLocked() needs

Rationale:
Refactors the way we set up optimization passes
in the compiler into a more centralized approach.
The refactoring also found some "holes" in the
existing mechanism (missing string lookup in
the debugging mechanism, or inablity to set
alternative name for optimizations that may repeat).

Remove all copies of 'MaybeRecordStat', replacing them with a single
OptimizingCompilerStats::MaybeRecordStat helper.

This patch refactors the way GraphChecker is invoked, utilizing the
same scoping mechanism as pass timing and graph visualizer. Therefore,
GraphChecker will now run not just after instances of HOptimization
but after the builders and reg alloc, too.

Adds a new pass which finds all unreachable blocks, typically due to
simplifying an if-condition to a constant, and removes them from the
graph. The patch also slightly generalizes the graph-transforming
operations.

- propagate reference types between instructions
- remove checked casts when possible
- add StackHandleScopeCollection to manage an arbitrary number of stack
handles (see comments)

Dex code can lead to the creation of a phi with one
float input and one integer input. Since the SSA builder trusts
the verifier, it assumes that the integer input must be converted
to float. However, when the register is not used afterwards, the
verifier hasn't ensured that. Therefore, the compiler must remove
the phi prior to doing type propagation.

Move gVerboseMethods to CompilerOptions. Now "--verbose-methods=" option to
dex2oat rather than runtime argument "-verbose-methods:".
Move ToStr and Dumpable out of logging.h, move LogMessageData into logging.cc
except for a forward declaration.
Remove ConstDumpable as Dump methods are all const (and make this so if not
currently true).
Make LogSeverity an enum and improve compile time assertions and type checking.
Remove log_severity.h that's only used in logging.h.
With system headers gone from logging.h, go add to .cc files missing system
header includes.
Also, make operator new in ValueObject private for compile time instantiation
checking.

- 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.
