1a69820d6d Make NEON ld/st pseudo instruction classes take the instruction itinerary as 
an argument, so that we can distinguish instructions with the same register
classes but different numbers of registers (e.g., vld3 and vld4).  Fix some
of the non-pseudo NEON ld/st instruction itineraries to reflect the number
of registers loaded or stored, not just the opcode name.

357e2fe748 Eliminate a 'tst' that immediately follows an 'and' 
by morphing the 'and' to its recording form 'andS'.

This is basically a test commit into this area, to
see whether the bots like me. Several generalizations
can be applied and various avenues of code simplification
are open. I'll introduce those as I go.

I am aware of stylistic input from Bill Wendling, about
where put the analysis complexity, but I am positive
that we can move things around easily and will find a
satisfactory solution.

2a6b987773 When a function-local value with function-local metadata uses gets RAUWed with a 
non-function-local value, it may result in the metadata no longer needing to be
function-local. Check for this condition, and clear the isFunctionLocal flag, if
it's still in the uniquing map, since any node in the uniquing map needs to have
an accurate function-local flag.

Also, add an assert to help catch problematic cases.

0718ff9be2 fix PR8102, a case where we'd copyValue from a value that we already 
deleted.  Fix this by doing the copyValue's before we delete stuff!

The testcase only repros the problem on my system with valgrind.

9c34a7831d Re-apply r113679, which was reverted in r113720, which added a paid of new instcombine transforms 
to expose greater opportunities for store narrowing in codegen.  This patch fixes a potential
infinite loop in instcombine caused by one of the introduced transforms being overly aggressive.
