093177d5cd The new LDR* instruction patterns should handle the necessary encoding of
operands in the TableGen'erated bits, so we don't need to do the additional
magic explicitly.

encoding tricks. Handle the 'imm doesn't fit in the insn' case.

11d03f690e Remove try/catch(...) from Win32/Signals.inc.
catch(...) is used in Win32/Signals.inc for catching Win32 structured
exceptions, but according to [1], this is wrong.

We can't simply change try/catch to __try/__finally, since this syntax is not
supported by MinGW. We can use __try/__finally on MSVC and __try1/__except1
macros on MinGW [2], but I think that that solution obfuscates the code too
much.

The use of try/catch(...) in Signals.inc makes it impossible to link
MinGW-compiled libSystem with llvm-gcc compiled executables. I propose that we
just remove try/catch(...) from Signals.inc, since the meaning of the code won't
change.

f4630ecc3f Tweaks to X86 instructions to allow the 'w' suffix in places it makes
sense, when the instruction takes the 16-bit ax register or m16 memory
location.  These changes to llvm-mc matches what the darwin assembler
allows for these instructions.  Done differently than in r117031 that
caused a valgrind error which was later reverted.

will accept versions that the darwin assembler allows.  Forms ending in "pi" and
forms without all the operands.

c95c1465fd 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.

0960a650b7 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.

explicit about the operands. Split out the different variants into separate

3a0e0715a5 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
