ca9c42c4da Added the first bits of the ARM target assembler to llvm-mc. For now it only 
parses the .word directive as 4 bytes and ARMAsmParser::ParseInstruction will
give an error is called.  Broke out the test of the .word directive into two
different test cases, one for x86 and one for arm.

b6aef5c867 Substantially speed up combiner-aa in the following ways: 
1. Switch from an std::set to a SmallPtrSet for visited chain nodes.
2. Do not force the recursive flattening of token factor nodes, regardless of
   use count.
3. Immediately process newly created TokenFactor nodes.

Also, improve combiner-aa by teaching it that loads to non-overlapping offsets
of relatively aligned objects cannot alias.

These changes result in a >5x speedup for combiner-aa on most testcases.

752195e3c6 Add early coalescing to liveintervals. This is work in progress and is known to miscompute some tests. Read it at your own rish, I have aged 10 year while writing this. 
The gist of this is if source of some of the copies that feed into a phi join is defined by the phi join, we'd like to eliminate them. However, if any of the non-identity source overlaps the live interval of the phi join then the coalescer won't be able to coalesce them. The early coalescer's job is to eliminate the identity copies by partially-coalescing the two live intervals.

90edac0e8b Change MCAsmStreamer to take an MCInstPrinter instead of a 
full AsmPrinter, and change TargetRegistry to keep track
of registered MCInstPrinters.

llvm-mc is still linking in the entire
target foo to get the code emitter stuff, but this is an
important step in the right direction.

6735b1c5c4 Storing a set of PATypeHolders is a bad idea because their sort order will 
change as types are refined. Remove abstract types from CheckedTypes when they
we're informed that they have been refined. The only way types get refined in
