DebugInfo: Remove dead code from old DebugLoc API
Remove old API for `DebugLoc` now that all the callers have been

the old API to the new one:
DebugLoc DebugLoc::getFromMDLocation(MDNode *)
=> DebugLoc::DebugLoc(MDLocation *)
=> explicit DebugLoc::DebugLoc(MDNode *) // works with broken code
MDNode *DebugLoc::getAsMDNode(LLVMContext &)
=> MDLocation *DebugLoc::get()
=> DebugLoc::operator MDLocation *()
=> MDNode *DebugLoc::getAsMDNode() // works with broken code
bool DebugLoc::isUnknown()
=> DebugLoc::operator MDLocation *()
i.e.: if (MDLocation *DL = ...)
=> DebugLoc::operator bool() // works with broken code
i.e.: if (DebugLoc DL = ...)
void DebugLoc::getScopeAndInlinedAt(MDNode *&, MDNode *&)
=> use: MDNode *DebugLoc::getScope()
and: MDLocation *DebugLoc::getInlinedAt()
MDNode *DebugLoc::getScopeNode(LLVMContext &)
=> MDNode *DebugLoc::getInlinedAtScope()
void DebugLoc::dump(LLVMContext &)
=> void DebugLoc::dump()
void DebugLoc::getFnDebugLoc(LLVMContext &)
=> void DebugLoc::getFnDebugLoc()
MDNode *DebugLoc::getScope(LLVMContext &)
=> MDNode *DebugLoc::getScope()
MDNode *DebugLoc::getInlinedAt(LLVMContext &)
=> MDLocation *DebugLoc::getInlinedAt()
I've noted above the only functions that won't crash on broken code (due
to downcasting to `MDLocation`). If your code could be dealing with
broken IR (i.e., you haven't run the verifier yet, or you've used a
temporary node that will eventually (but not yet) get RAUW'ed to an

The 'R' constraint is actually supposed to be much more complicated than
this and is defined in terms of whether it will cause macro expansion in
the assembler. 'R' is getting less useful due to architecture changes and
ought to be replaced by other constraints. We therefore implement 9-bit
offsets which will work for all subtargets and all instructions.

Revert "[SCEV] Look at backedge dominating conditions."
This leads to terribly slow compile times under MSAN. More discussion
on the commit thread of r233447.

[X86] Remove FeatureAES for 'corei7' CPU. 'corei7' should match 'nehalem' which doesn't have AES. Having AES and not PCLMUL makes 'corei7' halfway between Nehalem and Westmere.
