Fix for PR1108: type of insert_vector_elt index operand is PtrVT, not MVT::i32.

Clean up ARM PEI code.

Backend is reponsible for aligning the stack.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33388 91177308-0d34-0410-b5e6-96231b3b80d8

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.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33384 91177308-0d34-0410-b5e6-96231b3b80d8

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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33383 91177308-0d34-0410-b5e6-96231b3b80d8

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 ...
