d9e57c146d Fix MSVC warning: "is out of range for enum constant"
MSVC doesn't support 64 bit enum. 
OpcodeMask is not used anywhere in the code base.

328634598f Change the order of tBX's operands so that the predicate operands come after the
target register, matching BX. I filed this bug because I was confused at first:

69c19f7316 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.
