Fix lazy symbolication bug in RegionStore involving fields of global variables.  When invalidated, the entire
globals memory space gets assigned a symbolic value, but that value was not being used for lazy symbolication
of fields of globals.  This could result in cases where bogus null dereferences were being reported.

Fixes PR 8440.

Tweak null dereference checker to give better diagnostics for null dereferences resulting from array accesses.

do not double-count the duplicate instructions by counting once from the
beginning and again from the end.  Keep track of where the duplicates from
the beginning ended and don't go past that point when counting duplicates
at the end.  Radar 8589805.

This change causes one of the MC/ARM/simple-fp-encoding tests to produce
different (better!) code without the vmovne instruction being tested.
I changed the test to produce vmovne and vmoveq instructions but moving
between register files in the opposite direction.  That's not quite the same
but predicated versions of those instructions weren't being tested before,
so at least the test coverage is not any worse, just different.

instructions separately from the count of non-predicated instructions.  The
instruction count is used in places to determine how many instructions to
copy, predicate, etc. and things get confused if that count includes the
extra cost for microcoded ops.
