941aa7b1e8 Generalize the reading of probability metadata to work for both branches
and switches, with arbitrary numbers of successors. Still optimized for
the common case of 2 successors for a conditional branch.

Add a test case for switch metadata showing up in the BlockFrequencyInfo pass.

99d01c54a0 Teach the BranchProbabilityInfo analysis pass to read any metadata
encoding of probabilities. In the absense of metadata, it continues to
fall back on static heuristics.

This allows __builtin_expect, after lowering through llvm.expect
a branch instruction's metadata, to actually enter the branch
probability model. This is one component of resolving PR2577.

6aa5c26c81 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.

250c6801e4 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.

2532fa21a9 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).
