LiveInterval::MergeValueNumberInto instead of trying to extend LiveRanges and
getting it wrong.

This fixed PR8249 where a valno with a multi-segment live range was defined by
an identity copy created by RemoveCopyByCommutingDef. Some of the live
segments disappeared.

For example, on:

#include <emmintrin.h>
int foo(int N) {
 __m128i white2;
 white2 = _mm_slli_si128(white2, N);
 return 0;
} 

we used to get:
fatal error: error in backend: Cannot yet select: intrinsic %llvm.x86.sse2.psll.dq

now we get:

  To not skip long running tests, pass '-l' to the test driver (dotest.py).

  An example:

    @unittest2.skipIf(TestBase.skipLongRunningTest(), "Skip this long running test")
    def test_foundation_disasm(self):
        ...

o Added a long running disassemble test to the foundation directory, which iterates
  the code symbols from Foundation.framework and kicks off a disassemble command for
  for the named function symbol.  Found a crasher: rdar://problem/8504895.

o Plus added/updated some comments for the TestBase class.

Thread the determination of branch prediction hit rates back through the if-conversion heuristic APIs.  For now,
stick with a constant estimate of 90% (branch predictors are good!), but we might find that we want to provide
more nuanced estimates in the future.
