want to include llvm-tblgen in the install, look for llvm-config instead,
and use that to find llvm-tblgen.

Comment parsing: fix a bug where a line with whitespace between two paragraphs
would cause us to concatenate these paragraphs into a single one.
The no-op whitespace churn in test/Index test happened because these tests
don't use the correct approach for testing and are more strict than required
for they are testing.

CMake: build llvm-config on Windows.
It was previously not being built on Windows because the cmake file relied
on a sed script to generate a .in file that llvm-config needs.
By using cmake's configure_file function, we can get rid off the sed hack,
and also have this work on Windows.

Adds cyclic critical path computation and heuristics, temporarily disabled.
Estimate the cyclic critical path within a single block loop. If the
acyclic critical path is longer, then the loop will exhaust OOO
resources after some number of iterations. If lag between the acyclic
critical path and cyclic critical path is longer the the time it takes
to issue those loop iterations, then aggressively schedule for
latency.

MI Sched: record local vreg uses.
This will be used to compute the cyclic critical path and to
update precomputed per-node pressure differences.
In the longer term, it could also be used to speed up LiveInterval
update by avoiding visiting all global vreg users.

Debug mode for string. This commit also marks the first time libc++ debug-mode has found a bug (found one in regex). Had to play with extern templates a bit to get this to work since string is heavily used within libc++.dylib.
