Kevin Enderby ba985d9dd5 Added some aliases to the fcomip and fucompi Intel instructions. So that llvm-mc 
will accept versions that the darwin assembler allows.  Forms ending in "pi" and
forms without all the operands.

John McCall 6fe024052b Don't compute linkage for a declaration as part of the #pragma weak 
forward-declaration support unless there's really a mapping for that
name.

Jakob Stoklund Olesen 79e1407c11 Handle critical loop predecessors by making both inside and outside registers 
live out.

This doesn't prevent us from inserting a loop preheader later on, if that is
better.

Jakob Stoklund Olesen 795ed98180 Compute critical loop predecessors in the same way as critical loop exits. 
Critical edges going into a loop are not as bad as critical exits. We can handle
them by splitting the critical edge, or by having both inside and outside
registers live out of the predecessor.

Jakob Stoklund Olesen 0e7a011a00 Physical registers trivially have multiple connected components all the time. 
Only virtuals should be requires to be connected.

Caroline Tice 750cd1755d Clean up the API logging code: 
- Try to reduce logging to one line per function call instead of tw
      - Put all arguments & their values into log for calls
      - Add 'this' parameter information to function call logging, making it show the appropriate
        internal pointer (this.obj, this.sp, this.ap...)
      - Clean up some return values
      - Remove logging of constructors that construct empty objects
      - Change '==>' to '=>'  for showing result values...
      - Fix various minor bugs
      - Add some protected 'get' functions to help getting the internal pointers for the 'this' arguments...

Dale Johannesen e660f4d072 Use a MemIntrinsicSDNode for ISD::PREFETCH, which touches

into the MachineInstr yet).  No functional change except
for dump output.

Andrew Trick 5f88cc34e1 Remove the vector of live vregs. I thought we would need to track 
them, but hopefully we won't. And this is not the right data structure
to do it anyway.

Jim Grosbach 1e4d9a17c2 First part of refactoring ARM addrmode2 (load/store) instructions to be more 
explicit about the operands. Split out the different variants into separate
instructions. This gives us the ability to, among other things, assign
different scheduling itineraries to the variants. rdar://8477752.

Jakob Stoklund Olesen e4f3317cda After splitting, compute connected components of all new registers, not just for 
the remainder register.

Example:

bb0:
  x = 1
bb1:
  use(x)
  ...
  x = 2
  jump bb1

When x is isolated in bb1, the inner part breaks into two components, x1 and x2:

bb0:
  x0 = 1
bb1:
  x1 = x0
  use(x1)
  ...
  x2 = 2
  x0 = x2
  jump bb1
