f1b4eafbfe rename MVT::Flag to MVT::Glue. "Flag" is a terrible name for 
something that just glues two nodes together, even if it is
sometimes used for flags.

6e90ce21cc If we're not using reg+reg offset we're using reg+imm, set the opcode 
to be the one we want to use. bugpoint reduced testcase is a little large,
I'll see if I can simplify it down more.

a519d57725 Fix a copy-pasto. When the tBR_JTr instruction was converted to using the 
tPseudoInst class, its size was changed from "special" to "2 bytes". This is
incorrect because the jump table will no longer be taken into account when
calculating branch offsets.

8d0963f72c Add EdgeBundles to SplitKit. 
Edge bundles is an annotation on the CFG that turns it into a bipartite directed
graph where each basic block is connected to an outgoing and an ingoing bundle.
These bundles are useful for identifying regions of the CFG for live range
splitting.

2a6899c539 Add ADT/IntEqClasses.h as a light-weight implementation of EquivalenceClasses.h. 
This implementation already exists as ConnectedVNInfoEqClasses in
LiveInterval.cpp, and it seems to be generally useful to have a light-weight way
of forming equivalence classes of small integers.

IntEqClasses doesn't allow enumeration of the elements in a class.

43ff68ded0 Add a new convenience pass for testing InstructionSimplify. Previously 
it could only be tested indirectly, via instcombine, gvn or some other
pass that makes use of InstructionSimplify, which means that testcases
had to be carefully contrived to dance around any other transformations
that that pass did.

5337f20c15 Teach InstCombine to merge (icmp ult (X + CA), C1) | (icmp eq X, C2) into (icmp ult (X + CA), C1 + 1) if C2 + CA == C1. 
InstCombine creates these so now we compile x == 23 || x == 24 || x == 25 to
  %x.off = add i32 %x, -23
  %1 = icmp ult i32 %x.off, 3
instead of
  %x.off = add i32 %x, -23
  %1 = icmp ult i32 %x.off, 2
  %cmp3 = icmp eq i32 %x, 25
  %ret2 = or i1 %1, %cmp3

784a176bc3 New cmake option LLVM_APPEND_VC_REV for controlling when the VC 
revision id is appended to the LLVM version string. Defaults to
OFF.

Until now the VC revision id was always appended to the revision
string whenever cmake was invoked (either explicitly or implicitly
because a cmake source file changed). This was causing massive
recompilations because config.h are reconfigured with the new contents
of PACKAGE_VERSION.

23a0199f05 now that addc/adde are gone, "ADDC" in the X86 backend uses EFLAGS results,
