Use an explicit fp in dvmPlatformInvoke
When calling a JNI method we have to push a variable number of
arguments onto the stack. This confuses the stack unwinders in
gdb and debuggerd.
It turns out that the unroll tables consulted by debuggerd let
you specify a frame pointer register. If we set that up, we can
get a full debuggerd trace. gdb is still confused though.
We now need to preserve fp on entry, but we no longer need to save
off sp, and as a result of some additional register shuffling we
also no longer need to save r4 and r5.
