This patch adds a new TM method, ml_wt, which uses an array of locks with version numbers and runs a write-through algorithm with time-based validations and snapshot time extensions. patch1 adds xcalloc as a helper function for allocations (used in the new TM method). patch2 improves TM method reinitialization (helps ml_wt avoid reallocation of the lock array) and adds a hook to TM methods so that they can report back whether they can deal with the current runtime situation (e.g., a the current number of threads). patch3 is the actual TM method. Tested on ppc64 with up to 64 threads with both microbenchmarks and STAMP. OK for trunk?
