The latency based scheduling could induce spills in some cases.

Allow subtargets to customize the generic scheduling strategy.
This is convenient for targets that don't need to add new heuristics
by specializing the strategy.

The previous msbuild integration only worked if VS2010 was installed. This patch
renames the current integration to LLVM-vs2010 and adds LLVM-vs2012.

at all.

When running a make-based command, SATestBuild tries to append a -jN flag
with an appropriate N to run the build in parallel. However, it failed
to take into account that each line read includes a trailing newline
(unless it is the last line of a file without a trailing newline), which
resulted in the "-jN" appearing on a line on its own.

clang-modernize can now transform headers properly and the experimental
-headers option is no longer necessary.

Remember, at least -include is necessary for indicating which headers
are allowed to be changed.

From Jim's post on the lldb-dev mailing list:

  This code is there as a backstop for when the unwinder drops a frame at
  the beginning of new function/trampoline or whatever.

  In the (older_ctx_is_equivalent == false) case we will see if we are at
  a trampoline function that somebody knows how to get out of, and
  otherwise we will stop.

Occasionally DAGCombiner can spot that a SETCC operation is completely
redundant and reduce it to "all true" or "all false". If this happens to a
vector, the value produced has to take account of what a normal comparison
would have produced, which may be an all-1s bitmask.

The fix in SelectionDAG.cpp is tested, however, as far as I can see the code in
TargetLowering.cpp is possibly unreachable and almost certainly irrelevant when
triggered so there are no tests. However, I believe it's still clearly the
right change and may save someone else some hassle if it suddenly becomes
reachable. So I'm doing it anyway.

The architecture has many comparison instructions, including some that
extend one of the operands.  The signed comparison instructions use sign
extensions and the unsigned comparison instructions use zero extensions.
In cases where we had a free choice between signed or unsigned comparisons,
we were trying to decide at lowering time which would best fit the available
instructions, taking things like extension type into account.  The code
to do that was getting increasingly hairy and was also making some bad
decisions.  E.g. when comparing the result of two LLCs, it is better to use
CR rather than CLR, since CR can be fused with a branch while CLR can't.

This patch removes the lowering code and instead adds an operand to
integer comparisons to say whether signed comparison is required,
whether unsigned comparison is required, or whether either is OK.
We can then leave the choice of instruction up to the normal isel code.
