Reduce stack usage for overflow checks
This reduces the stack space reserved for overflow checks to 12K, split
into an 8K gap and a 4K protected region. GC needs over 8K when running
in a stack overflow situation.
Also prevents signal runaway by detecting a signal inside code that
resulted from a signal handler invokation. And adds a max signal count to
the SignalTest to prevent it running forever.
Also reduces the number of iterations for the InterfaceTest as this was
taking (almost) forever with the --trace option on run-test.

Fix crash in VirtualMachine.AllThreads JDWP command
When collecting all the started threads, we may encounter a thread in the
process of being started from Java code (Thread.start) in the threads list. The
crash occurs when we attempt to access the java.lang.Thread peer (calling
Thread::GetPeer) but the JNI global reference to it (Thread::jpeer) has not
been destroyed yet (which is verified with a check). This only happens when the
thread is starting up.
We now check the thread finished starting up before accessing the Java peer.
This also prevents from returning non-started threads in the reply.

ART: Fix memory unmapped twice issue in ElfFile::Load(bool)
Root Cause:
The overlapped memory region will be unmapped by
(1) ~MemMap() of reservation MemMap (reserve) and
(2) ~MemMap() of "reuse" MemMap (segment).
Someone takes the memory region after (1) and it will be unmapped in (2).
So, SIGSEGV occurs when using the unmapped memory region.
Solution:
Fixes this issue by skip unmap "reuse" MemMap in destructor.
And always create reservation MemMap before "reuse" MemMap. (It also solved
the fixupELF case which does not reserve the whole needed memory region).
