Kalle Raiskila a49d062234 Change v64 datalayout in SPU. 
The SPU ABI does not mention v64, and all examples
in C suggest v128 are treated similarily to arrays, 
we use array alignment for v64 too. This makes the 
alignment of e.g. [2 x <2 x i32>] behave "intuitively"
and similar to as if the elements were e.g. i32s.

This also makes an "unaligned store" test to be 
aligned, with different (but functionally equivalent)
code generated.

NAKAMURA Takumi 4bb599cf7d CMake: Build utils/KillTheDoctor only on MSVC for now. 
Mingw does not have the header <dbghelp.h>.
Thanks to Daniel Newton, testing it on mingw.

Bob Wilson e1961fe289 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.

Bob Wilson efd360c535 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.
