13b475d4f6 Add pass printing support to BlockFrequencyInfo pass. The implementation 
layer already had support for printing the results of this analysis, but
the wiring was missing.

Now that printing the analysis works, actually bring some of this
analysis, and the BranchProbabilityInfo analysis that it wraps, under
test! I'm planning on fixing some bugs and doing other work here, so
having a nice place to add regression tests and a way to observe the
results is really useful.

29934af872 Duncan pointed out that sometimes CC and CXX are used to specify the compiler. Also that the configure script takes care of finding an appropriate compiler if one's not specified.

d2a8c29880 projects/sample: Import adapted form of current LLVM autoconf/Makefile setup so that projects/sample is standalone and not tied to the LLVM build setup. 
- This currently just moves over all of the behavior from LLVM. Eventually all of the configure checks that are directly needed by the LLVM build setup should probably go away, and the project should manage their own configuration checks if necessary.

 - This is the 1st half of this work, the actual Makefile.common hasn't moved over yet. I've tried to stage this in such a way that incremental builds will properly reconfigure for most active developers (the Makefiles don't handle reconfiguring in a perfectly reliable way, and I haven't found an easy way to make them do so).

da2d6a83c8 Use the integer compare when the value is small enough. Use the "move into a 
register and then compare against that" method when it's too large. We have to
move the value into the register in the "movw, movt" pair of instructions.

92050387bb A landing pad could have more than one predecessor. In that case, we want that 
predecessor to remove the jump to it as well. Delay clearing the 'landing pad'
flag until after the jumps have been removed. (There is an implicit assumption
in several modules that an MBB which jumps to a landing pad has only two
successors.)
