499d77553a Added support for machine specific constantpool values. These are useful for 
representing expressions that can only be resolved at link time, etc.

c35e7175c3 An sinkable instruction may exist with uses, if those uses are in dead blocks.

f82eb13e3b 1) With X86 lowering change, the following can no longer happen since 
the branch's chain is also produced by cmp.
          [ch, r : ld]
             ^ ^
             | |
      [XX]--/   \- [flag : cmp]
       ^             ^
       |             |
       \---[br flag]-

Remove an isel check which prevents loads from being folded into cmp / test
instructions.

2) Whenever possible, delete a selected node to allow more load folding
opportunities. Note not all nodes can be deleted after it has been
selected. Some may have simply morphed; some have not changed at all (e.g.
EntryToken).

cfd7b147cf X86ISD::CMP now produces a chain as well as a flag. Make that the chain 
operand of a conditional branch to allow load folding into CMP / TEST
instructions.

2921612126 Allow tail duplication in more cases, relaxing the previous restriction a 
bit.  This fixes Regression/Transforms/TailDup/MergeTest.ll

480465a171 This code was trying too hard. By eliminating redundant edges in the CFG 
due to switch cases going to the same place, it make #pred != #phi entries,
breaking live interval analysis.

This fixes 458.sjeng on x86 with llc.

3bfe103166 Replace EquivalenceClasses with a custom-built data structure. Many common 
operations (like findProperties) should be faster, at the expense of
unionSets being slower in cases that are rare in practise.

Don't erase a dead Instruction. This fixes a memory corruption issue.

2dfa13e74f First pass at supporting relocations. Relocations are written correctly to 
the file now, however the relocated address is currently wrong.  Fixing
that will require some deep pondering.
