5109456c75 DebugInfo: PR14728: TLS support
Based on GCC's output for TLS variables (OP_constNu, x@dtpoff,
OP_lo_user), this implements debug info support for TLS in ELF. Verified
that this output is correct/sufficient on Linux (using gold - if you're
using binutils-ld, you'll need something with the fix for
http://sourceware.org/bugzilla/show_bug.cgi?id=15685 in it).

Support on non-ELF is sort of "arbitrary" at the moment - if Apple folks
want to discuss (or just go ahead & implement) how this should work in
MachO, etc, I'm open.

3648e54a41 DebugInfo: Pass MCSymbolRefExprs for labels instead of MCSymbols
This is a precursor to adding debug info support for TLS which requires
non-default relocations applied to TLS symbols.

7f9144ae20 Fix a PPC rlwimi instruction-selection bug
Under certain (evidently rare) circumstances, this code used to convert OR(a,
AND(x, y)) into OR(a, x). This was incorrect.

While there, I've added a comment to the code immediately above.

b47853a3be Add flag to lli to enable debugging of IR when used with MCJIT.
- warn users when -debug-ir is used with old JIT engine (only partial debug
  info is available) 

For example, to debug an IR file with GDB (that supports JIT registration), do:

$ gdb --args lli -use-mcjit -debug-ir testcase.ll
(gdb) break main
(gdb) run
<Process continues to lli main>
(gdb) continue
<Process continues to testcase.ll main()
(gdb) step
<Now stepping through the LLVM IR in testcase.ll>

e8b20c4f7b Add missing case to switch statement - DAGTypeLegalizer::ExpandIntegerResult
should expand ATOMIC_CMP_SWAP nodes the same way that it does for ATOMIC_SWAP.

Since ATOMIC_LOADs on some targets (e.g. older ARM variants) get legalized to
ATOMIC_CMP_SWAPs, the missing case had been causing i64 atomic loads to crash
during isel.

a9465b9413 Add a division operator to BlockFrequency.
Allow a BlockFrequency to be divided by a non-zero BranchProbability
with saturating arithmetic. This will be used to compute the frequency
of a loop header given the probability of leaving the loop.

Our long division algorithm already saturates on overflow, so that was a
freebie.

09766b6b9f LoopVectorize: Use static function instead of DebugLocSetter class
I used the class to safely reset the state of the builder's debug location.  I
think I have caught all places where we need to set the debug location to a new
one. Therefore, we can replace the class by a function that just sets the debug
location.

e13264c995 ARM: ensure fixed-point conversions have sane types
We were generating intrinsics for NEON fixed-point conversions that didn't
exist (e.g. float -> i16). There are two cases to consider:
  + iN is smaller than float. In this case we can do the conversion but need an
    extend or truncate as well.
  + iN is larger than float. In this case using the NEON conversion would be
    incorrect so we don't perform any combining.

5bedd08922 Debug Info: clean up usage of Verify.
No functionality change.
It should suffice to check the type of a debug info metadata, instead of
calling Verify. For cases where we know the type of a DI metadata, use
assert.

Also update testing cases to make them conform to the format of DI classes.

8eae838533 Improvements to unique_file and createUniqueDirectory.
* Don't try to create parent directories in unique_file. It had two problem:
   * It violates the contract that it is atomic. If the directory creation
     success and the file creation fails, we would return an error but the
     file system was modified.
   * When creating a temporary file clang would have to first check if the
     parent directory existed or not to avoid creating one when it was not
     supposed to.

* More efficient implementations of createUniqueDirectory and the unique_file
  that produces only the file name. Now all 3 just call into a static
  function passing what they want (name, file or directory).

Clang also has to be updated, so tests might fail if a bot picks up this commit
and not the corresponding clang one.
