448db1cdef 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.

5edca81626 Fixed a bug where the disassembler would allow an immediate 
argument that had to be between 0 and 7 to have any value,
firing an assert later in the AsmPrinter.  Now, the
disassembler rejects instructions with out-of-range values
for that immediate.

f8b5c63617 VHADD differs from VHSUB at least on A9 - the former reads both operands in the second cycle, while the latter reads second operand in first cycle. Introduce new itin classes to catch this behavior. Whether this is true for A8 as well is WIP.
