Try/Catch analysis; various workarounds

Fixed a couple of codegen bugs.  Added a temporary workaround until
SSA renaming problem is fixed.  By enabling the "CompileDexLibCore"
test in compiler_test.cc and disabling the jni_compiler, we appear to
be successfully compiling 17,641 methods of libcore (note: of those,
4 exhibit the SSA problem).

Also turned off most of the compiler logging, and disabled the fast
path for invoke virtual (which seems to be broken).
