11fa8d0f62 If dynamic_stackalloc alignment is > stack alignment, first issue an instruction to align the stack ptr before the decrement.

9a05381a81 - If a dynamic_stackalloc alignment requirement is <= stack alignment, then the alignment argument is ignored.
- *Always* round up the size of the allocation to multiples of stack
alignment to ensure the stack ptr is never left in an invalid state after a dynamic_stackalloc.

4c6c787315 This adds a bunch of static functions that implement unsigned
two's complement bignum arithmetic.  They could be used to
implement much of APInt, but the idea is they are enough to
implement APFloat as well, which the current APInt interface
is not suited for.

056b656f99 Improve error handling in the linker by:
1. Eliminate redundant error messages. LinkInFile and LinkInArchive
   already call the error() method in each case so there's no use
   telling the user again that an item couldn't be linked in.

2. Improve the formatting of error messages (separating content).

3. Change the wording for the warning about unrecognized files. Make
   it clear that the file is being ignored.

f758fa5c35 If the source of a move is in spill slot, the reload may be folded to essentially a load from stack slot. It's ok to mark the stack slot value as available for reuse. But it should not be clobbered since the destination of the move is live.

de24ad8897 If a spilled value is being reused and the use is a kill, that means there are
no more uses within the MBB and the spilled value isn't live out of the MBB.
Then it's safe to delete the spill store.
