This reduces the size of the pre-header by 8 bytes, reducing
oat file size and mmapped .text section size. The memory
needed to store a CompiledMethod by dex2oat is also reduced,
for 32-bit dex2oat by 8B and for 64-bit dex2oat by 16B. The
aosp_flounder-userdebug 32-bit and 64-bit boot.oat are each
about 1.1MiB smaller.

Disable the broken StubTest.IMT, b/27991555 .

35831e8bfa1c0944d4c978d99c4c5b9577945170 11-Sep-2015 Vladimir Marko <vmarko@google.com> Reduce memory used by CompiledMethods.

Use LengthPrefixedArray<>s instead of SwapVector<>s to store
CompiledMethod data and get rid of the unnecessary members
of CompiledMethod to reduce dex2oat memory usage. Refactor
the deduplication from CompilerDriver to a new class.

Use HashSet<> instead of std::set<> for the DedupeSet<> to
further decrease the memory usage and improve performance.

This reduces the dex2oat memory usage when compiling boot
image on Nexus 5 (with Optimizing, -j1) by ~6.75MiB (5%).
This also reduces the compile time by ~2.2% (~1.6% dex2oat
time; with Optimizing, without -j).

This adds the ability to track where we allocate memory
when the kArenaAllocatorCountAllocations flag is turned on.

Also move some allocations from native heap to the Arena
and remove some unnecessary utilities.

was IMT.

66cdcbeeedc6e51b4c56da6969ce193b8c520bbc 06-Mar-2015 Mathieu Chartier <mathieuc@google.com> Fix incompatible class change error for JIT stress mode

There was a problem with miranda methods, when we would dequicken to
one of these, it wouldn't resolve as virtual during the method
lowering resolve. The solution is to try resolving as interface if we
fail to resolve as virtual.

Fixed a bug in dequickening where unreachable register lines with
quick invokes would cause CHECK failuers. In this case we punt to the
interpreter (test 435-try-*).

Added test regression test. Example failure:
java.lang.IncompatibleClassChangeError: The method
'void Main$TheInterface.m()' was expected to be of type virtual but
instead was found to be of type interface (declaration of
'java.lang.reflect.ArtMethod' appears in
