Mike Stump 38013e109e Temporary flip default for -Wunreachable-code so some bots can test it
out.  They should all be done later tonight, but if something bad
happens, feel free to revert sooner.

Anders Carlsson d0849254de Baby steps towards migrating the InitListChecker over to the new initialization code. Pass an InitializedEntity pointer through to most init checker functions. Right now, it's ignored everywhere except when initializing vectors in C++.

Chris Lattner 29b15c5cfd third bug from PR6119: the xor dupe extension allows
for arbitrary terminators in predecessors, don't assume
it is a conditional or uncond branch.  The testcase shows
an example where they can happen with switches.

Nick Lewycky 32966aed9d Teach DAE that even though it can't modify the function signature of an
externally visible function, it can still find all callers of it and replace
the parameters to a dead argument with undef.

Chris Lattner ba2d0b89ff add an early out to ProcessBranchOnXOR to speed it up,
handle the case when we can infer an input to the xor
from all inputs that agree, instead of going into an
infinite loop.  Another part of PR6199

Bill Wendling 8cbc25d945 Remove the '-disable-scheduling' flag and replace it with the 'source' option of
the '-pre-RA-sched' flag. It actually makes more sense to do it this way. Also,
keep track of the SDNode ordering by default. Eventually, we would like to make
this ordering a way to break a "tie" in the scheduler. However, doing that now
breaks the "CodeGen/X86/abi-isel.ll" test for 32-bit Linux.

John McCall 6d174646dd Produce a special diagnostic when users call a function with an argument of
incomplete type (or a pointer/reference to such).

The causes of this problem are different enough to justify a different "design"
for the diagnostic.  Most notably, it doesn't give an operand index:
it's usually pretty obvious which operand is the problem, it adds a lot of
clutter to mention it, and the fix is usually in a different part of the file
anyway.

This is yet another diagnostic that should really have an analogue in the
non-overloaded case --- which should be much easier to write because of
the weaker space constraints.

Chris Lattner 76bdea3290 resolve a fixme: the "nonexecutable stack directive" is actually
a .section.  Switch to it with SwitchSection.

However, I think that this directive should be safe on any ELF target.
If so, we should hoist it up out of the X86 and SystemZ targets.

John McCall fe796ddd5a During overload resolution diagnostics, sort non-viable candidates by the quality of their
conversions.  To make this work, fill out all conversions for all candidates
(but only when diagnosing overload failure).  Split out a few cases from
ovl_fail_bad_conversion which didn't actually involve a failed argument
conversion.

I'm pretty sure this is not a well-founded ordering, but I'm not sure it matters.
