e696436a7e CMake: Add a new configuration option LLVM_BUILD_CLANG that's 
available when Clang is found within the LLVM tree. If enabled (the
default), Clang will be built as part of LLVM. If disabled, Clang will
be skipped... and can be built by configuring a separate object
directory just for Clang. This helps break up the monolithic
LLVM+Clang project that many Clang developers use, improving
build/load times.

5196c12e9f Add a new field to MCOperandInfo that contains information about the type of the Operand. 
- The actual values are from the MCOI::OperandType enum.
- Teach tblgen to read it from the instruction definition.
- This is a better implementation of the hacks in edis.

d0f3ef807e [VECTOR-SELECT] 
During type legalization we often use the SIGN_EXTEND_INREG SDNode.
When this SDNode is legalized during the LegalizeVector phase, it is
scalarized because non-simple types are automatically marked to be expanded.
In this patch we add support for lowering SIGN_EXTEND_INREG manually.
This fixes CodeGen/X86/vec_sext.ll when running with the '-promote-elements'
flag.

672b93a332 Unfortunately several files in MC are badly violating layering rule by using

other cases of violations, but this is probably the worst.

This patch is but one small step towards fixing this. 500 more steps to go. :-(

f1c709837b Reapply r135121 with a fixed copy constructor. 
Original commit message:

Count references to interference cache entries.

Each InterferenceCache::Cursor instance references a cache entry. A
non-zero reference count guarantees that the entry won't be reused for a
new register.

This makes it possible to have multiple live cursors examining
interference for different physregs.

The total number of live cursors into a cache must be kept below
InterferenceCache::getMaxCursors().

Code generation should be unaffected by this change, and it doesn't seem
to affect the cache replacement strategy either.
