a6cad8869f Fix Transforms/InstCombine/2006-12-05-fp-to-int-ext.ll, fixing an out-of- 
stack-space issue in the ppc bootstrap.

c87c3e5a70 Bail on the getInferredCast idea. Remove the function and convert 
remaining uses to more specific casts.

28a5079f58 Can't make these fail now with just BitCast. Previous failures must have 
been in conjunction with something else. By right, they should just be
BitCasts.

2d2a26767e Implement new cast creation functions for both instructions and constant 
expressions. These will get used to reduce clutter as we replace various
calls to createInferredCast and getCast.

4cb4234c17 Take a baby step towards getting rid of inferred casts. Provide methods on 
CastInst and ConstantExpr that allow the signedness to be explicitly passed
in and reliance on signedness removed from getCastOpcode. These are
temporary measures useful during the conversion of inferred casts.

1b0e89e022 Start moving pass registration over to using the ManagedStatic mechanism. 
This fixes issues where passes get unregistered before llvm_shutdown is
called, and is generally cleaner and simpler.  Analysis groups up next.

a2bd5d4aaa move 'cfgonly' pass tracking into PassInfo, instead of handling it with 
yet-another global data structure.

64b24381a8 These should be rewritten to fold without using the 'Rules' mechanism, but 
until this happens at least make sext from bool and sitofp from bool do the
right thing.

7e0d6868fd this logic is broken for trunc to bool, replace the folding logic for trunc 
completely, as it is trivial.  We should probably do this for the rest of the
cast operations.  This fixes ConstProp/2006-12-01-TruncBoolBug.ll.

c65612e859 Fix a typo introduced by the cast patch that horribly broke a lot of vector

a1613b631b Don't fold "ptrtoint GV to bool" since this should be doing a truncate not 
a comparison against zero. Instead fold setne(GV,null) and seteq(GV,null)
to ConstantBool::True or ConstantBool::False, respectively.

992d9788b3 For PR950: 
The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

6e34ef887b For PR950: 
First in a series of patches to convert SetCondInst into ICmpInst and
FCmpInst using only two opcodes and having the instructions contain their
predicate value. Nothing uses these classes yet. More patches to follow.
