Fix libarttest to be non debug
Previously both libarttest and libarttestd had debug enabled. This
made it hard to know which one was loaded (couldn't look at
kIsDebugBuild).
Fixes test 136 with ART_TEST_RUN_TEST_NDEBUG configuration.

Split profile recording from jit compilation
We still use ProfileInfo objects to record profile information. That
gives us the flexibility to add the inline caches in the future and the
convenience of the already implemented GC.
If UseJIT is false and SaveProfilingInfo true, we will only record the
ProfileInfo and never launch compilation tasks.

Fix 570-checker-osr test for non-debuggable mode.
For non-debuggable mode, we need to create profiling info.

Fix inlining loops in OSR mode.
When compiling a method in OSR mode and the method does not
contain a loop (arguably, a very odd case) but we inline
another method with a loop and then the final DCE re-runs
the loop identification, the inlined loop would previously
be marked as irreducible. However, the SSA liveness analysis
expects irreducible loop to have extra loop Phis which were
already eliminated from the loop before the inner graph was
inlined to the outer graph, so we would fail a DCHECK().
We fix this by not marking inlined loops as irreducible when
compiling in OSR mode.

Be a bit smarter with JIT code triggering deoptimization.
Do not re-use an OSR method that triggered deoptimization.
Also add a stack overflow check before doing OSR.

Re-enable OSR.
1) Fix flaky test by doing explicit ProfilingInfo allocation,
and OSR compilation instead of relying on the system. Also
make sure the method $noinline$inlineCache always starts
with the interpreter, as otherwise we would infinite loop.
2) Ensure the thread doing the OSR cannot be suspended once it
holds an OSR method, as otherwise the jit code cache could
delete the method before the thread had a chance to jump to it.

Re-enable OSR.
Fixes two bugs:
- Dealing with proxy methods, which the compiler and code cache
does not handle.
- Dealing with phi types, that may have been speculatively optimized
but do not hold once jumping to the compiled code.

Implement on-stack replacement for arm/arm64/x86/x86_64.
High-level overview:
- osr_method_threshold is used to know when to compile a method
in osr mode (-> treat all loops as irreducible).
- branch instructions in the compiler query whether they can
jump to an osr method.
- An osr entry point is found through the stack maps: if a stack
map is duplicated in the CodeInfo, it is an osr entry point.
