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.

We now do the two-step memory protection strategy (first protect the
from space with PROT_READ and later protect it with PROT_NONE) only if
the from space is a rosalloc space (excluding the more common bump
pointer space case). This strengthens the GC verification for the bump
pointer space case as we avoid the case where mutators run while the
from space is PROT_READ rather than PROT_NONE.
Add a command line flag to override the minimum interval for the
hspace compaction for OOM and set it to zero in the gcstress/gcverify
run-tests to run the hspace compaction more frequently in tests.
Fix some comments.

Comment in arm_lir.h says:
* If a 64-bit argument would span the register/memory argument
* boundary, it will instead be fully passed in the frame.
This change implements such logic for all platforms. We still need
to pass the low part in register as well because I haven't ported
the jni compilers (x86 and mips) to it.
Once the jni compilers are updated, we can remove the register
assignment.
Note that this greatly simplifies optimizing's register allocator
by not having to understand a long spanning register and memory.

The solution works by doing the dump in 2 passes.
The first pass calculates the size of the dump.

size, then does the rest of the hprof dump by streaming and sending

- When splitting a low (or high) interval, we also split the high
(or low) equivalent.
- Allocation follows the (S/D register) requirement that low

ART: Print INTERNAL_FATAL Log messages immediately
To diagnose some problems, print out messages sent to Severity level
INTERNAL_FATAL immediately. This avoids the buffering we do.

Fix signal test to work with gcstress
We now avoid running GC if we are handling a stack overflow, this
helps prevent running past the end of the stack overflow reserved
bytes.
Added logic in ThrowStackOverflowError to use a stack overflow
exception without a stack trace if we fail to allocate the stack
trace.

Mathieu Chartier [Sat, 20 Dec 2014 02:41:47 +0000 (18:41 -0800)]
Don't allow suspension from FindLocksAtDexPc
Transitioning to suspended from runnable sometimes runs dump
checkpoints in ThreadStress which can cause deadlocks. This happens
since FindLocksAtDexPC runs the verifier which calls
AllowThreadSuspension. This results in a blocked thread which holds
the monitor lock, and if another thread tries to do a monitor enter,
it deadlocks while holding the mutator lock (assuming the GC is
suspending all).
The fix for avoiding this deadlock is not calling
AllowThreadSuspension from FindLocksAtDexPc.
