Fix an invoke-interface bug that manifests itself with thread state warnings.
r12 is a scratch register and apparently gcc 4.4 starts to actively use it in
dvmFindInterfaceMethodInCache, the very function that the original live value
is being protected around. This results in useless values setup in the chaining
cell and increases the chances to patch the cell (thus the suspend-all
requests).
Add verbose names for new JIT-related suspend reasons.
With all these changes, the thread state warning will still occur but much less
frequently.
bug 2194174.
