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.

Switch the llvm::Triple class to immediately parse the triple string on
...
construction. Simplify its interface, implementation, and users
accordingly as there is no longer an 'uninitialized' state to check for.
Also, fixes a bug lurking in the interface as there was one method that
didn't correctly check for initialization.

It turns out that with the current scev organization ReuseOrCreateCast cannot
...
know where users will be added. Because of this, it cannot use
Builder.GetInsertPoint at all.
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.

ecx = mov eax
al = mov ch
The second copy is not a nop because the sub-indices of ecx,ch is not the

--------------- < Insertion point
but that complicates the callers. This fixes PR12018 (and firefox's build).
