1e213ff3c0 Added LUAJIT_TRACEPROFILE 
Trace profiling takes regular samples of the program counter and uses
them to maintain three new counters for each trace:

  nonloop: Samples taken when running the non-loop part of the trace
  loop:    Samples taken when running the loop part of the trace
  other:   Samples taken outside the trace mcode (e.g. FFI calls)

Trace profiling can be enabled and disabled with:

  jit.traceprofile.start(interval)
  jit.traceprofile.stop()

The current counter values for a trace can be queried via an extension
to the JIT introspection API:

  jit.util.tracestats(tr) => nonloop, loop, other

The overall intention of these counters is to enable development of
trace-oriented profiling tools, including self-profiling programs that
can identify suspicious traces to flush (e.g. traces that are biased
away from the root trace).

02b9b55976 Revert "OSX: Switch to Clang as the default compiler." 
It breaks cross-compilation to Android.
And host "gcc" aliases to "clang", anyway.
