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.

da1f5b882a For PR950: 
This patch converts the old SHR instruction into two instructions,
AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not
dependent on the sign of their operands.

87f79d5d69 Add a new helper method to SwitchInst. Useful when you've got a BB from 
somewhere (like the dominator graph) and would like to know which case it
came from.

Add support for specifying alignment and size of setjmp jmpbufs.

No targets currently do anything with this information, nor is it presrved
in the bytecode representation.  That's coming up next.

7eb45f89a5 Eliminate the explicit volatile fields in LoadInst and StoreInst. This shrinks 
LoadInst from 60 -> 56 bytes and StoreInst from 76 -> 72 bytes.

Note however, that this doesn't actually save any memory on common systems
where 'malloc' returns 8-byte aligned memory, as the saved space is replaced
by useless alignment padding.  :(
