introduce a new recoverable error handling API to LLVMContext
...
and use it in one place in inline asm handling stuff. Before
we'd generate this for an invalid modifier letter:
$ clang asm.c -c -o t.o
fatal error: error in backend: Invalid operand found in inline asm: 'abc incl ${0:Z}'
INLINEASM <es:abc incl ${0:Z}>, 10, %EAX<def>, 2147483657, %EAX, 14, %EFLAGS<earlyclobber,def,dead>, <!-1>
Now we generate this:
$ clang asm.c -c -o t.o
error: invalid operand in inline asm: 'incl ${0:Z}'
asm.c:3:12: note: generated from here
__asm__ ("incl %Z0" : "+r" (X));
^
1 error generated.
This is much better but still admittedly not great ("why" is the operand
invalid??), codegen should try harder with its diagnostics :)

Generalize IVUsers to track arbitrary expressions rather than expressions
...
explicitly split into stride-and-offset pairs. Also, add the
ability to track multiple post-increment loops on the same expression.
This refines the concept of "normalizing" SCEV expressions used for
to post-increment uses, and introduces a dedicated utility routine for
normalizing and denormalizing expressions.
This fixes the expansion of expressions which are post-increment users
of more than one loop at a time. More broadly, this takes LSR another
step closer to being able to reason about more than one loop at a time.
