Fixed an issue in the platform options where if no architecture was specified where the platform would fail to select itself with something like:

(lldb) platfrom select remote-ios

to selection DAG isel if we're unable to handle a non-double multi-reg retval.

This fixes a TODO from 2007 :) Previously, LLVM would emit the wrong
code here (see the update to test/CodeGen/X86/tls-pie.ll).

Added the missing bit definition for the 4th bit of the STR (post reg) instruction. It is now set to 0. The patch also sets the unpredictable mask for SEL and SXTB-type instructions.

Fixed the LLVM ARM v7 assembler and instruction printer for 8-bit immediate offset addressing. The assembler and instruction printer were not properly handeling the #-0 immediate.

Add a test case for going through typedefs until we reach "BOOL", that NSAPI::isObjCTypedef() is doing.

This patch will optimize the following cases:
  sub r1, r3 | sub r1, imm
  cmp r3, r1 or cmp r1, r3 | cmp r1, imm
  bge L1

TO
  subs r1, r3
  bge  L1 or ble L1

If the branch instruction can use flag from "sub", then we can replace
"sub" with "subs" and eliminate the "cmp" instruction.

Modified the symbolication.Image object to store its uuid as a uuid.UUID object and made an accessor for getting a normalized UUID value out of the image object.

Modified the crashlog darwin module to always create a uuid.UUID object when making the symbolication.Image objects. Also modified it to handle some more types of crash log files and improved the register reading for thread registers of crashed threads.

Don't intercept the quit command and override what is was doing. This was causing the "lldb" command line to deadlock when the quit command was executed sometimes.

"--stack-history" now works if you have MallocStackLogggingNoCompact defined in your app's environment.

The sub-registers explicitly listed in SubRegs in the .td files form a
tree. In a complicated register bank, it is possible to have
sub-register relationships across sub-trees. For example, the ARM NEON
double vector Q0_Q1 is a tree:

  Q0_Q1 = [Q0, Q1],  Q0 = [D0, D1], Q1 = [D2, D3]

But we also define the DPair register D1_D2 = [D1, D2] which is fully
contained in Q0_Q1.

This patch teaches TableGen to find such sub-register relationships, and
assign sub-register indices to them. In the example, TableGen will
create a dsub_1_dsub_2 sub-register index, and add D1_D2 as a
sub-register of Q0_Q1.

This will eventually enable the coalescer to handle copies of skewed
sub-registers.
