9d36acf9ec Cleanup ConstantFoldCompareInstruction: 
1. Make the arguments const like the other ConstantFold* functions.
2. Clean up evaluateFCmpRelation so it makes sense for floating point.
3. Implement the use of evaluateFCmpRelation to fold floating point CEs
4. Shorten a variable name so more things fit on one line.
5. Fix various comments.

193df25eb9 For PR1066: 
Fix this by ensuring that a bitcast is inserted to do sign switching. This
is only temporarily needed as the merging of signed and unsigned is next
on the SignlessTypes plate.

266e42b312 For PR950: 
This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

4e0c2a0e41 Just print integer constants as signed values. The actual signedness 
doesn't matter as it is determined in the way the constant is used.

e3068403bd At the beginning of run, initialize analyis info availability for _ALL_ 
pass managers. Otherwise, stale available analysis info, from the managers not
yet run, may cause pass manager to take wrong turn.

This fixes CBE test failures reported by nightly tester.

3f46fbaa00 Allow negative constants for unsigned integers and unsigned constants 
greater than MAX_INT64 for signed integers. This is now valid and is just
waiting for the distinction between signed and unsigned to go away.

1847f6ddbd handle undef values much more carefully: generalize the resolveundefbranches 
code to handle instructions as well, so that we properly fold things like
X & undef -> 0.
This fixes Transforms/SCCP/2006-12-19-UndefBug.ll
