a9e552182a Teach the legalizer to propagate the original alignment of loads and store when 
it splits them.

9401b2fcab On x86-64, the 32-bit cmov doesn't actually clear the high 32-bit of 
its result if the condition is false.

e9572a945b Add an "original alignment" field to load and store nodes. This enables the 
DAG Combiner to disambiguate chains for loads and stores of types which are
 broken up by the Legalizer into smaller pieces.

83bb285c97 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.

f43d8a08b0 Pull the creation of the "RewindFunction" function out of the loop. It's only 
created once, so shouldn't be stuck in the middle of the loop. Also early exit
if there are no uses of UnwindInst in the function.

4a33f01892 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.

9b6c23aba0 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
the verifier is when later function passes start optimizing. Fixes PR4970.
