Enable multi-threaded Quick compilation

Reuse thread-local copies of llvm context data for Quick compiler
(while continuing to regenerate fresh ones per method for Portable).
This is a transitional CL - the upcoming compiler driver change
is expected to pass pass a thread context structure to each compiler
worker thread rather than use the pthread_key mechanism.
