34e6148dc8 Handle a corner case when extracing code regions where one of the immediate successor 
of an extracted block contains a PHI using a value defined in the extracted region.

c635f47d9a For PR950:

1. [US]Byte -> Int8

4. [U]Long  -> Int64.

   identifying the signedness information from other sources.

56273827b1 If we are extracting a block that has multiple successors that are the same 
block (common in a switch), make sure to remove extra edges in successor
blocks.  This fixes CodeExtractor/2004-08-12-BlockExtractPHI.ll and should
be pulled into LLVM 1.3 (though the regression test need not be, as that
would require pulling in the LoopExtract.cpp changes).

3b2917bfcf * Pull some code out into the definedInRegion/definedInCaller methods 
* Add a stub for the severSplitPHINodes which will allow us to bbextract
  bb's with PHI nodes in them soon.
* Remove unused arguments from findInputsOutputs
* Dramatically simplify the code in findInputsOutputs.  In particular,
  nothing really cares whether or not a PHI node is using something.
* Move moveCodeToFunction to after emitCallAndSwitchStatement as that's the
  order they get called.
* Fix a bug where we would code extract a region that included a call to
  vastart.  Like 'alloca', calls to vastart must stay in the function that
  they are defined in.

ffc4926263 Generate substantially better code when there are a limited number of exits 
from the extracted region.  If the return has 0 or 1 exit blocks, the new
function returns void.  If it has 2 exits, it returns bool, otherwise it
returns a ushort as before.

This allows us to use a conditional branch instruction when there are two
exit blocks, as often happens during block extraction.

3d1ca67fdd Two minor improvements: 
1. Get rid of the silly abort block.  When doing bb extraction, we get one
     abort block for every block extracted, which is kinda annoying.
  2. If the switch ends up having a single destination, turn it into an
     unconditional branch.

I would like to add support for conditional branches, but to do this we will
want to have the function return a bool instead of a ushort.
