Test updates were performed using:
https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34
These are only the test updates where the test passed without
further modification (which is almost all of them, as the backend
is largely pointer-type agnostic).
TargetMachine::shouldAssumeDSOLocal currently implies dso_local for such definitions.
Adding explicit dso_local makes these tests align with the clang -fno-pic behavior
and allow the removal of the TargetMachine::shouldAssumeDSOLocal special case.
This re-applies commit r292189, reverted in r292191.
SelectionDAGBuilder recognizes libfuncs using some homegrown
parameter type-checking.
Use TLI instead, removing another heap of redundant code.
This isn't strictly NFC, as the SDAG code was too lax.
Concretely, this means changes are required to a few tests:
- calling a non-variadic function via a variadic prototype isn't OK;
it just happens to work on x86_64 (but not on, e.g., aarch64).
- mempcpy has a size_t parameter; the SDAG code accepts any integer
type, which meant using i32 on x86_64 worked.
- a handful of SystemZ tests check the SDAG support for lax prototype
checking: Ulrich agrees on removing them.
I don't think it's worth supporting any of these (IMO) invalid
testcases. Instead, fix them to be more meaningful.

I don't think it's worth supporting either of these (IMO) broken
testcases. Instead, fix them to be more correct.

Patch by Sunita Marathe
Third try, now following fixes to MSan to handle mempcy in such a way that this commit won't break the MSan buildbots. (Thanks, Evegenii!)
