Use the target-aware constant folder on expressions to improve the chance
...
they'll be simple enough to simulate, and to reduce the chance we'll encounter
equal but different simple pointer constants.
This removes the symptoms from PR11352 but is not a full fix. A proper fix would
either require a guarantee that two constant objects we simulate are folded
when equal, or a different way of handling equal pointers (ie., trying a
constantexpr icmp on them to see whether we know they're equal or non-equal or
unsure).

InstCombine: Don't transform a signed icmp of two GEPs into a signed compare of the indices.
...
This transformation is not safe in some pathological cases (signed icmp of pointers should be an
extremely rare thing, but it's valid IR!). Add an explanatory comment.
Kudos to Duncan for pointing out this edge case (and not giving up explaining it until I finally got it).

Pull the parsing helper functions out of the Triple interface entirely.
...
They're private static methods but we can just make them static
functions in the implementation. It makes the implementations a touch
more wordy, but takes another chunk out of the header file.
Also, take the opportunity to switch the names to the new coding
conventions.
No functionality changed here.

Clear virtual registers after they are no longer referenced.
...
Passes after RegAlloc should be able to rely on MRI->getNumVirtRegs() == 0.
This makes sharing code for pre/postRA passes more robust.
Now, to check if a pass is running before the RA pipeline begins, use MRI->isSSA().
To check if a pass is running after the RA pipeline ends, use !MRI->getNumVirtRegs().
PEI resets virtual regs when it's done scavenging.
PTX will either have to provide its own PEI pass or assign physregs.

This patch
* removes the FIXME about adding the assert.
* adds a comment explaining hy we don't have one.
* removes a broken logic that only works for some callers and is not needed
since r150884.
* adds an assert to caller that would have caught the bug fixed by r150884.
