This fix allows to use non-constant global variables, static local variables and static data

Bill Schmidt pointed out that some adjustments would be needed to properly
support powerpc64le (using the ELF V2 ABI). For one thing, R11 is not available
as a scratch register, so we need to use R12. R12 is also available under ELF
V1, so to maintain consistency, I flipped the order to make R12 the first
scratch register in the array under both ABIs.

The target may be a synthetic symbol like __ImageBase.  cast_or_null will ensure
that the atom is a DefinedAtom, which is not guaranteed, which was the original
reason for the cast_or_null.  Switch this to dyn_cast, which should enable
building of executables for WoA.  Unfortunately, the issue of missing base
relocations still needs to be investigated.

the register state when debugging AArch32 programs (armv7
programs running on an armv8 processor).  Most notably,
there is no "fpscr" register in the register context -
there is an fpsr and an fpcr.

Also fix a bug where the floating point values could not
be written in armv7 processes.

This isn't actually used for anything, and is broken on Darwin
(currently causing build failures now that the triple is passed to aid
cross compiling). Rather than fix unused code, just remove it.

This reverts commit r226173, adding r226038 back.

No change in this commit, but clang was changed to also produce trivial comdats for
costructors, destructors and vtables when needed.

Original message:

Don't create new comdats in CodeGen.

This patch stops the implicit creation of comdats during codegen.

Clang now sets the comdat explicitly when it is required. With this patch clang and gcc
now produce the same result in pr19848.

IRCE eliminates range checks of the form

  0 <= A * I + B < Length

by splitting a loop's iteration space into three segments in a way
that the check is completely redundant in the middle segment.  As an
example, IRCE will convert

  len = < known positive >
  for (i = 0; i < n; i++) {
    if (0 <= i && i < len) {
      do_something();
    } else {
      throw_out_of_bounds();
    }
  }

to

  len = < known positive >
  limit = smin(n, len)
  // no first segment
  for (i = 0; i < limit; i++) {
    if (0 <= i && i < len) { // this check is fully redundant
      do_something();
    } else {
      throw_out_of_bounds();
    }
  }
  for (i = limit; i < n; i++) {
    if (0 <= i && i < len) {
      do_something();
    } else {
      throw_out_of_bounds();
    }
  }


IRCE can deal with multiple range checks in the same loop (it takes
the intersection of the ranges that will make each of them redundant
individually).

Currently IRCE does not do any profitability analysis.  That is a
TODO.

Please note that the status of this pass is *experimental*, and it is
not part of any default pass pipeline.  Having said that, I will love
to get feedback and general input from people interested in trying
this out.

This pass was originally r226201.  It was reverted because it used C++
features not supported by MSVC 2012.

`ninja lldb` used to always run "echo -n", which on OS X results in literally
echoing "-n" to the screen.  Just remove the command from add_custom_target,
then it only adds an alias and `ninja lldb` now reports "no work to do".

Other than that, no intended behavior change.

This produces comdats for vtables, typeinfo, typeinfo names, and vtts.

When combined with llvm not producing implicit comdats, not doing this would
cause code bloat on ELF and link errors on COFF.

Instructions with 1 operand can still use source modifiers,
