75edc6b6e0 implement support for 'clr' alias. This is part of rdar://8416805, 
but balrog was wanting it on irc.

9297448bed New cmake options LLVM_INCLUDE_X (X = {TOOLS, EXAMPLES, TESTS}) for 
not generating build targets for those parts of the build.

2291919711 Avoid warnings about implicit conversions to `bool' in MSVC. This time 
for real.

40caeda472 Reverting "CMake: Don't include tools, unittets, or examples as 
available targets unless LLVM_INCLUDE_X is ON. LLVM_BUILD_X implies
LLVM_INCLUDE_X"

It breaks the configuration phase when cmake is invoked without
parameters, it is too complex for the purpose and introduces an
incovenience for the user (as both LLVM_BUILD_X and LLVM_INCLUDE_X
must set to OFF for not including X on the build)

856fcd57d1 LoadPRE was not properly checking that the load it was PRE'ing post-dominated the block it was being hoisted to. 
Splitting critical edges at the merge point only addressed part of the issue; it is also possible for non-post-domination
to occur when the path from the load to the merge has branches in it.  Unfortunately, full anticipation analysis is
time-consuming, so for now approximate it.  This is strictly more conservative than real anticipation, so we will miss
some cases that real PRE would allow, but we also no longer insert loads into paths where they didn't exist before. :-)

This is a very slight net positive on SPEC for me (0.5% on average).  Most of the benchmarks are largely unaffected, but
when it pays off it pays off decently: 181.mcf improves by 4.5% on my machine.

7dec569dfa If we're changing the source of a memcpy we need to use the alignment 
of the source, not the original alignment since it may no longer
be valid.

702c4ef9d8 MC/AsmParser: Support .single and .double for embedding floating point literals.
