548f5a0b75 Add support for using the `!if' operator when initializing variables: 
class A<bit a, bits<3> x, bits<3> y> {
    bits<3> z;
    let z = !if(a, x, y);
  }

The variable z will get the value of x when 'a' is 1 and 'y' when a is '0'.

1fbf5a492e Fix paths; AutoRegen.sh changes its current working directory to be the 
autoconf directory, but these paths need to be relative to the main
source directory.  Patch originally by Dan Gohman, r67655.

Also, cause configure.ac to find absolute paths to LLVM source and
object trees.   Together, fixes PR1220.

eb13382333 1. Change MBlaze indirect branches to use absolute branch BRALD instead of pc relative branch BRLD. 
2. Make sure that the MBlaze stack is aligned to 4-byte boundaries.
3. Determine frame indexes that should be placed in the callers stack frame, as per the MBlaze ABI, and place them in the correct locations.

2f7228b80c Generalize the and-icmp-select instcombine further by allowing selects of the form 
(x & 2^n) ? 2^m+C : C

we can offset both arms by C to get the "(x & 2^n) ? 2^m : 0" form, optimize the
select to a shift and apply the offset afterwards.

f6dff84d4e Force the greedy register allocator to always use the inline spiller. 
Soon, RegAllocGreedy will start splitting live ranges, and then deferred
spilling won't work anyway.

3bda29eb4f Rip out live range splitting support from the inline spiller. 
The spiller should only spill. The register allocator will drive live range
splitting, it has the needed information about register pressure and
interferences.
