- Build debug metadata for 'bare' Modules using DIBuilder
- DebugIR can be constructed to generate an IR file (to be seen by a debugger)
  or not in cases where the user already has an IR file on disk.

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.

- Use static functions instead of anonymous namespace.
- Appease the Doxygen lobby.
- Use 0-based induction variable.

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.

[NVPTX] Clean up comparison/select/convert patterns and factor out PTX instructions from their patterns

Test case is no breakage

[NVPTX] Remove i8 register class.  PTX support for i8 (.b8, .u8, .s8) is rather poor and we're better off just ignoring it and letting LLVM expand all i8 ops out to i16.

Don't check for "are there any loaded sections" before trying to resolve a breakpoint site.  We've already got a process,
and any breakpoints with section relative addresses won't resolve their load addresses so they will error out at that point.

sys::fs::unique_file will now loop infinitely if provided with a file name
without '%' characters and the input file already exists. As a result, bugpoint
cannot use a fixed file name for the execution output (including the reference
output).

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.

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.

The mapping between SRS pseudo-instructions and SRS native instructions was incorrect, the correct mapping is:

srsea -> srsia
