If we try to reuse a failure, we'll be holding a NULL Method* without
the current thread having the appropriate exception pending, which will
lead to a SIGSEGV.
I've added a corresponding vm-test to cts/.

An leading underscore followed by a capital letter is a reserved
name space in C and C++.
This change also moves any #include directives within the include
guard in some of the compiler/codegen/arm header files.

Convert some ANDROID_MEMBAR_FULL uses into equivalent atomic ops. A
couple of "bool" had to convert to "int" since we don't have atomic
ops for bools.
Replaced a local implementation of atomic inc with a call to the
atomic inc function.

Fix some SMP correctness issues in the VM:
- Correct AtomicCache implementation, inserting barriers where needed
and correcting existing usage.
- Emphasize that String startup isn't expected to be reentrant, and
use atomic ops to ensure that we explode if anybody tries it.
- Use 64-bit quasiatomic ops to manage the "last activity" timer in
JDWP. (Also, provide some documented but unimplemented behavior.)
- Updated the volatile operations in sun.misc.Unsafe to include
appropriate barriers.
(This does not purport to correct all SMP issues, just some of the
more obvious ones.)
