70213c7c5f Replace the -unwind-tables option with a per function flag. This is more
LTO friendly as we can now correctly merge files compiled with or without
-fasynchronous-unwind-tables.

9466b36c02 Fix LoopUnswitch bug. RewriteLoopBodyWithConditionConstant can delete a dead
case of a switch instruction. Back off this optimization when this would
eliminate all of the predecessors to the latch.

Sorry, I am unable to reduce a reasonably sized test case.

1084ac5bb1 Implement the rest of the SEH directive-parsing methods in the COFFAsmParser.

more descriptive error message to the .seh_handler directive parser.

6ddbe02441 Change StackDirection from StackGrowsUp to StackGrowsDown.
The following improvements are accomplished as a result of applying this patch:
- Fixed frame objects' offsets (relative to either the virtual frame pointer or
  the stack pointer) are set before instruction selection is completed. There is
  no need to wait until Prologue/Epilogue Insertion is run to set them.
- Calculation of final offsets of fixed frame objects is straightforward. It is
  no longer necessary to assign negative offsets to fixed objects for incoming
  arguments in order to distinguish them from the others.
- Since a fixed object has its relative offset set during instruction
  selection, there is no need to conservatively set its alignment to 4.
- It is no longer necessary to reorder non-fixed frame objects in 
  MipsFrameLowering::adjustMipsStackFrame.
