Log Message:
-----------
x86: Fix instruction selector deadlock in invoke()
The instruction selector can deadlock during compilation if method A
invokes method B and the same method B also invokes method A. Fix that
by using pthread_mutex_trylock() and treating the target method as not
compiled of the mutex is under contention.
Fixes the following deadlock found by helgrind:
==5206== Thread #1: lock order "0x4A4C0CC before 0x18A9F5A4" violated
==5206== at 0x40264B7: pthread_mutex_lock (hg_intercepts.c:408)
