ART: Loosen a GraphChecker rule on Boolean inputs
GraphChecker tries to verify that Boolean inputs are properly typed.
This is non-trivial in the presence of simplifying optimizations
which capitalize on the fact that a Boolean value is internally
represented as an integer.
This patch removes the test from GraphChecker.

Optimizing: Do not insert suspend checks on back-edges.
Rely on HGraph::SimplifyLoop() to insert suspend checks.
CodeGenerator's CheckLoopEntriesCanBeUsedForOsr() checks the
dex pcs of suspend checks against branch targets to verify
that we always have an appropriate point for OSR transition.
However, the HSuspendChecks that were added by HGraphBuilder
to support the recently removed "baseline" interfered with
this in a specific case, namely an infinite loop where the
back-branch jumps to a nop. In that case, the HSuspendCheck
added by HGraphBuilder had a dex pc different from the block
and the branch target but its presence would stop the
HGraph::SimplifyLoop() from adding a new HSuspendCheck with
the correct dex pc.

ART: Improve JitProfile perf in arm/arm64 mterp
ART currently requires two profiling-related things from the
interpreters: hotness updates and OSR switch checks. The hotness
updates previously used the existing instrumentation framework - which
is flexible, but quite heavyweight. For most things, the
instrumentation framework overhead is acceptable, but because we do a
hotness update on every backwards branch the overhead is unacceptable.
Prior to this CL, branch profiling dominates interpreter cost.
Here, we bypass the instrumentation framework for hotness updates
and deliver a significant performance improvement. Running
interpreter-only (dalvikvm -Xint) on a Nexus 6, we see the logic
subtest of Caffeinemark improving from 2600 to 9200, and the
overall score going from 1979 to over 3000. Compared to the
C++ switch interpreter, we see a 6x improvement on the branchy logic
subtest and a 2.6x improvement overall.
Compared with the previous mterp which did not have support for
jit profiling, we see a few (1% to 5%) performance loss on the
standard command-line benchmarks. I consider this acceptable
(we could create an alternate non-profiling mterp which would
have no penalty, but I don't consider this overhead big enough to
justify that).

Improve ProfileSaver to cache data and do minimal I/O
This CLs introducing caching to further optimize the I/O performed by
the ProfileSaver. The cache stats are also recorded.
Resolved classes are captured and cached after 2 seconds but written
later during application lifetime.
Methods are also cached and the write got smarter to avoid
reading/writing them if it's not needed.
On non scientific experiments the size of the cache reaches just a few
hundreds uint16_t values kept in set, so its impact is minimal.
In terms of how much data we write. In the same non scientific
experiments this reduces the total bytes written by at least 2-3x. In
the first few minutes of after the boot gmscore writes ~3KB (down from
9kb) and quicksearchlauncher writes ~20KB (down from 40KB).
