The encoding of NOP in ARMAsmBackend.cpp is missing a trailing zero, which
causes the emission of a coprocessor instruction rather than "mov r0, r0"
as indicated in the comment.  The test also checks for the wrong encoding.

For OS X builds, we generate one version of config.h but then build for
multiple architectures.  This means that the LLVM_HOSTTRIPLE setting may have
the wrong architecture.  Adjust it dynamically to match the current
architecture.  <rdar://problem/12715470>

This is for the lldb team so most of but not all of the values are
to be printed as hex with this option.  Some small values like the
scale in an X86 address were requested to printed in decimal
without the leading 0x.

There may be some tweaks need to places that may still be in
decimal that they want in hex.  Specially for arm.  I made my best
guess.  Any tweaks from here should be simple.

I also did the best I know now with help from the C++ gurus
creating the cleanest formatImm() utility function and containing
the changes.  But if someone has a better idea to make something
cleaner I'm all ears and game for changing the implementation.

- Added calls to doInitialization/doFinalization to immutable passes
- fixed ordering of calls to doFinalization to be the reverse of the pass run order due to potential dependencies
- fixed machine module info to operate in the doInitialization/doFinalization model, also fixes some FIXMEs

  This change attempts to simplify (X^Y) -> X or Y in the user's context if we know that
only bits from X or Y are demanded.

  A minimized case is provided bellow. This change will simplify "t>>16" into "var1 >>16".

  =============================================================
  unsigned foo (unsigned val1, unsigned val2) {
    unsigned t = val1 ^ 1234;
    return (t >> 16) | t; // NOTE: t is used more than once.
  }
  =============================================================

  Note that if the "t" were used only once, the expression would be finally optimized as well.
However, with with this change, the optimization will take place earlier.

The count attribute is more accurate with regards to the size of an array. It
also obviates the upper bound attribute in the subrange. We can also better
handle an unbound array by setting the count to -1 instead of the lower bound to
1 and upper bound to 0.

This reapplies the fix for PR13303 now with more justification. Based on my
execution of the GDB 7.5 test suite this results in:

expected passes: 16101 -> 20890 (+30%)
unexpected failures: 4826 -> 637 (-77%)

There are 23 checks that used to pass and now fail. They are all in
gdb.reverse. Investigating a few looks like they were accidentally passing
due to extra breakpoints being set by this bug. They're generally due to the
difference in end location between gcc and clang, the test suite is trying to
set breakpoints on the closing '}' that clang doesn't associate with any
instructions.

on 64-bit PowerPC ELF.

The patch includes code to handle external assembly and MC output with the
integrated assembler.  It intentionally does not support the "old" JIT.

For the initial-exec TLS model, the ABI requires the following to calculate
the address of external thread-local variable x:

 Code sequence            Relocation                  Symbol
  ld 9,x@got@tprel(2)      R_PPC64_GOT_TPREL16_DS      x
  add 9,9,x@tls            R_PPC64_TLS                 x

The register 9 is arbitrary here.  The linker will replace x@got@tprel
with the offset relative to the thread pointer to the generated GOT
entry for symbol x.  It will replace x@tls with the thread-pointer
register (13).

The two test cases verify correct assembly output and relocation output
as just described.

PowerPC-specific selection node variants are added for the two
instructions above:  LD_GOT_TPREL and ADD_TLS.  These are inserted
when an initial-exec global variable is encountered by
PPCTargetLowering::LowerGlobalTLSAddress(), and later lowered to
machine instructions LDgotTPREL and ADD8TLS.  LDgotTPREL is a pseudo
that uses the same LDrs support added for medium code model's LDtocL,
with a different relocation type.

The rest of the processing is straightforward.
