7c730e7790 When the "true" and "false" blocks of a diamond if-conversion are the same,
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.

2ad40d3494 Change if-conversion to keep track of the extra cost due to microcoded
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.

05897c8f26 ATTRIBUTE_UNUSED has been renamed to LLVM_ATTRIBUTE_UNUSED.
Rather than rename this instance, use the cast-to-void idiom
instead.  This will hopefully fix the windows buildbots.

10d3191cf1 Remove deprecated macro names. Hopefully this will unbreak the
smooshlab build.  The breakage seems to be due to a collision
between LLVM's ATTRIBUTE_UNUSED and gcc's which was previously
hidden due to header files being included in a lucky order.
