<rdar://problem/4283967> REGRESSION: 3% regression on PLT from new FastMalloc
​http://bugzilla.opendarwin.org/show_bug.cgi?id=5243

A number of optimizations to the new threadsafe malloc that make it actually as fast
as dlmalloc (I measured wrong before) and as memory-efficient as the system malloc.

• use fastMalloc for everything - it now gets applied to all new/delete allocations via a private inline operator new that is now included into every file via config.h.

• tweaked some of the numeric parameters for size classes and amount of wasted memory allowed per allocation - this saves on memory use and consequently improves speed.

• so long as the allocator is not being used on background threads, get the per-thread cache from a global variable instead of from pthread_getspecific, since the latter is slow.

• inline more functions, and force the ones GCC refuses to inline with attribute(always_inline), nearly all of these have one call site so inlining them has to be a win.

• use some tricks to calculate allocation size more efficiently and fewer times for small allocations, to avoid hitting the huge size table array.

• avoid hitting the per-thread cache on code paths that don't need it.

• implement inline assembly version of spinlock for PowerPC (was already done for x86)
