ART: Invoke Checker from run-test scripts
This patch moves Checker-based tests of the optimizing compiler into
the art/test directory and modifies the run-test scripts to dump
the CFG during compilation and to verify the graph using Checker as
part of the "running" stage. Outputs generated by running the test
and running Checker are concatenated and compared with expected.txt.
Checker is invoked only if the test's name name matches the format
"<number>-checker-*" and it's currently enabled only for optimizing +
host configs. The tests are still invoked on other configs but
without Checker.

calculation to keep track of the number of core registers and number of

This is slightly pessimal, as the registers may not be active at the

classes of registers simultaneously, or remember all the active
intervals, matching them up and compute the size of each safepoint
interval.

Then, it makes a false alarm (process crash) on thread suspend timeout when doing ComputeRelativeTimeSpec.
if (ComputeRelativeTimeSpec(&rel_ts, end_abs_ts, now_abs_ts)) {
return false; // Timed out.
}
Solution:
Use CLOCK_MONOTONIC instead

Fix wide volatile IGET/IPUT on ARM without atomic ldrd/strd.
If ldrd/strd isn't atomic, IPUT_WIDE uses ldrexd+strexd and
we need to record the safepoint for the ldrexd rather than
strexd. IGET_WIDE was simply missing the memory barrier.

JDWP: fix deadlock with GC
This CL fixes a deadlock where JDWP thread and running GC thread are
waiting for each other. Here is the sequence of the deadlock:
1. GC thread disables access to weak global references, then releases
mutator lock.
2. JDWP thread takes mutator lock exclusively after suspending all
threads.
3. GC thread waits for shared mutator lock which is held by JDWP
thread.
4. JDWP thread clears weak global references but need to wait for GC
thread to re-enable access to them.
To avoid that situation, we ensure the JDWP thread does not attempt
to delete weak global references while holding the mutator
exclusively so GC thread is not blocked.

ART: dex2oat flag for HGraphVisualizer dump file
This patch adds a new '--dump-cfg=<file>' flag to dex2oat which
specifies the file that HGraphVisualizer will store its output into.
Until now the graph was dumped to 'art.cfg' in the current working
directory. To make Checker work with run-test, the output directory
needs to be customizable.

Fix bootclasspath string initialization
When running the runtime with an image without explicitly specifying
the bootclasspath (with the -Xbootclasspath option), we construct it
from the location of DEX files loaded from the image.
This allows to fix the JDWP test ClassPathsTest#testClassPaths001 on
the host where the bootclasspath is not explicitly specified on the
command line.
