ART: Fix overlapping instruction IDs in inliner
Inliner creates the inner graph so that it generates instruction IDs
higher than the outer graph. This was broken because the inliner
would create instructions in the outer graph before the inner graph
is inlined.
The bug cannot be triggered because the offending instruction would
share the same ID as the first inner HLocal, which is removed before
the inner graph is inlined. The added DCHECKs reveal the hidden problem
and make it safe for HLocals to be removed in the future.

Add lz4hc image compression format
Smaller than lz4 and decompresses at the same speed. Compression is
a bit slower.
Example saves on old FB APK:
Uncompressed:
44748800 bytes
LZ4:
12443648 bytes
LZ4HC:
11055104 bytes
Generating the image slows down by ~1s per 20MB of image due to
slower compression. Decompression is about the same speed but there
should be a slight speedup since less data needs to be read from
flash.
Added test.

Revert "Revert "ART: Support interpreter switching in x86 mterp""
Fixes the invoke template. Previously, it was permitting
an interpreter switch *before* advancing the Dalvik PC.
This meant that on a switch, the invoke would be interpreted
twice.
This reverts commit

Optimizing: ARM64 negated bitwise operations simplification
Use negated instructions on ARM64 to replace [bitwise operation + not]
patterns, that is:
a & ~b (BIC)
a | ~b (ORN)
a ^ ~b (EON)
The simplification only happens if the Not is only used by the bitwise
operation. It does not happen if both inputs are Not's (this should be
handled by a generic simplification applying De Morgan's laws).
