be06428ba3 Try to appease MSVC even more elaborately in the alignment hacking space.
MSVC doesn't support passing by-value parameters with alignment of
16-bytes or higher apparantly. What is deeply confusing is that it seems
to *sometimes* (but not always) apply this to any type whose alignment
is set using __declspec(align(...)). This caused lots of errors when we switch
SmallVector over to use the automatically aligned character array
utilities as they used __declspec(align(...)) heavily.

As a pretty horrible but effective work-around, we instead cherry pick
the smallest alignment sizes with specific types that happen to have the
correct alignment, and then fall back to the attribute solution past
them. This should resolve the MSVC build errors folks have been hitting.
Sorry for that. In good news, it will do this without introducing other
UB I hope. =]

Thanks to Timur Iskhodzhanov for helping me test this!

912519a72e Heed guessInstructionProperties, and stop warning on redundant flags.
Emit TableGen errors if guessInstructionProperties is 0 and
instruction properties can't be inferred from patterns.

Allow explicit instruction properties even when they can be inferred.

This patch doesn't change the TableGen output. Redundant properties
are not yet verified because the tree has errors.

f104bf65b9 Add CodeGenTarget::guessInstructionProperties.
Currently, TableGen just guesses instruction properties when it can't
infer them form patterns.

This adds a guessInstructionProperties flag to the instruction set
definition that will be used to disable guessing. The flag is intended
as a migration aid. It will be removed again when no more targets need
their properties guessed.

ffd2526fa4 Simplify the computeOperandLatency API.

operand indices. This ensures consistent use of the machine model's
