Expect less in the presence of a string init call.
The compiler currently relies on the dex cache being populated
for doing proper type propagation. If it hasn't, we may end up in the
situation where the DexMethodInliner has recognized a String.<init> call
(because DexMethodInliner only looks at signatures, and does not resolve
types), but the graph builder doesn't see a type and assume it needs
to do access checks and clinit checks on it.

dynamic deoptimization to eliminate bounds checks in e.g. a[0],
a[1], a[2], etc. This CL generalizes this to any symbolic base
with offset in e.g. a[base], a[base+1], etc. The runtime tests

Match a constructor chain where each constructor either

followed by any number of IPUTs on "this", storing either

When collecting IPUTs from the constructor chain, remove
any IPUTs that store the same field as an IPUT that comes
later. This is safe in this case even if those IPUTs store
volatile fields because the uninitialized object reference
wasn't allowed to escape yet. Also remove any IPUTs that

Fixes: missing sign extension in iget template

Missing export PCs
Reworks: Branch handlers to reduce cost of branch profiling.
Re-enables Jit profiling for both Arm and Arm64.
Performance note:
Branch profiling is relatively expensive, though the real
cost will depend on branch frequency. Taking a very
branch intensive benchmark, CaffeineMark's logic test, we
see the following scores (higher is better):
Mterp (profiling off) 6187
Mterp (profiling on) 4305
Switch (profiling off) 3931
Switch (profiling on) 2032

Some clean-up for the handling of HSelect in LSE
Use $noinline and throwing an Exception for doing no-inlining in
the test.
Also create reference info early for HSelect if it has reference
type, which may help the pre-existence-based alias analysis.

Make it possible to enable native debugging through debug flags
* Add support for a new debug flag disabling the optimizations in
the compiler and enable the generation of some additional debug
info (--native-debuggable).
* Ignore the content of the oat files if force JIT is enabled so
the runtime ignores the AOT-ed code what doesn't contain any
debug info.
