0ca73b9208 Enable -split-phi-edges by default, except when -regalloc=local. 
The local register allocator doesn't like it when LiveVariables is run.
We should also disable edge splitting under -O0, but that has to wait a bit.

fe3a0fccb9 Remove a special case for tail merging that seems to be both broken and 
unnecessary.  It is broken because the "isIdenticalTo" check should be
negated.  If that is fixed, this code causes the CodeGen/X86/tail-opts.ll
test to fail, in the dont_merge_oddly function.  And, I confirmed that the
regression is real -- the generated code is worse.  As far as I can tell,
that tail-opts.ll test is checking for what this code is supposed to handle
and we're doing the right thing anyway.

f3f063a58e Revert CPU detection code to return "generic" instead of an empty string in case 
of failure. The x86 target didn't like empty cpu names and broke x86 tests on
non-x86 buildbots.

eaa8a9aa98 Perform tail duplication only once, after tail merging is complete.

consistent.

3ced5472c3 1. Allow SCCIterator to work with GraphT types that are constant. 
2.  Allow SCCIterator to work with inverse graphs.
3.  Fix an incorrect comment in GraphTraits.h (the type in the comment 
was given as GraphType* when it is actually const GraphType &).

e36c429c3b "XFAIL" the Split2 StringReft test with Apple gcc, which miscompiles it. 
- I plan on fixing/workarounding this, but until then I'd like the bots to stay

bebe645914 Following a suggestion of Daniel Dunbar, stop people passing the name 
as the isSigned bool to CreateIntCast by having this resolve to a call
to a private method, rather than by using a gcc attribute.

block.

fc21555ca5 Remove the optimizations that convert BRCOND and BR_CC into 
unconditional branches or fallthroghes. Instcombine/SimplifyCFG
should be simplifying branches with known conditions.

This fixes some problems caused by these transformations not
updating the MachineBasicBlock CFG.

d530046ed3 Set Rm bits of BX_RET to 0b1110 (R14); and set condition code bits of BRIND to 
0b1110 (ALways).  This is so that the disassembler decoder can distinguish among
BX_RET, BRIND, and BXr9.
