they don't match.

Clean up ARM PEI code.

Backend is reponsible for aligning the stack.

We not align the final stack slot but instead let the target do so in emitPrologue(). Each target can make adjustments to the stack frame and re-align the stack as it deem appropriate. Do not align it twice which can end up wasting stack space.

Fix a #include to resolve IntegerType class.

Add a #include to resolve IntegerType class.

Add test case extracted from lencod. Spiller was infinite looping in GetRegForReload().

GetRegForReload() now keeps track which registers have been considered and rejected during its quest to find a suitable reload register. This avoids an infinite loop in case like this:
  t1 := op t2, t3
  t2 <- assigned r0 for use by the reload but ended up reuse r1
  t3 <- assigned r1 for use by the reload but ended up reuse r0
  t1 <- desires r1
        sees r1 is taken by t2, tries t2's reload register r0
        sees r0 is taken by t3, tries t3's reload register r1
        sees r1 is taken by t2, tries t2's reload register r0 ...

Help the lli interpreter find the stderr/stdin/stdout symbols. These are
needed for output to be generated. On Linux these are both global vars and
macro definitions so we have to special case Linux.

Handle each of stderr/stdin/stdout separately.

Remove dead methods in the ValTypes.

For this transform: store V, (cast P) -> store (cast V), P
don't allow the transform if V and the pointer's element type are different
width integer types.

For PR1043:
This is the final patch for this PR. It implements some minor cleanup
in the use of IntegerType, to wit:
1. Type::getIntegerTypeMask -> IntegerType::getBitMask
2. Type::Int*Ty changed to IntegerType* from Type*
3. ConstantInt::getType() returns IntegerType* now, not Type*

This also fixes PR1120.

Make this test actually test what its supposed to test.
