ef0bedaba7 Implement hasComputableLoopEvolution for Add, Mul, and Trunc operators, 
since they can support trivial implementations. This avoids potentially
expensive traversals of the operands.

335db22392 Add a 'normalize' method to the Triple class, which takes a mucked up 
target triple and straightens it out.  This does less than gcc's script
config.sub, for example it turns i386-mingw32 into i386--mingw32 not
i386-pc-mingw32, but it does a decent job of turning funky triples into
something that the rest of the Triple class can understand.  The plan
is to use this to canonicalize triple's when they are first provided
by users, and have the rest of LLVM only deal with canonical triples.
Once this is done the special case workarounds in the Triple constructor
can be removed, making the class more regular and easier to use.  The
comments and unittests for the Triple class are already adjusted in this
patch appropriately for this brave new world of increased uniformity.

b68f274b6d Don't use unsigned char for alignments in TargetData. There aren't 
that many of these things, so the memory savings isn't significant,
and there are now situations where there can be alignments greater
than 128.

9db3ea46cb Implement register class inflation. 
When splitting a live range, the new registers have fewer uses and the
permissible register class may be less constrained. Recompute the register class
constraint from the uses of new registers created for a split. This may let them
be allocated from a larger set, possibly avoiding a spill.

df30cf9e61 Transpose the calculation of spill weights such that we are calculating one 
register at a time. This turns out to be slightly faster than iterating over
instructions, but more importantly, it allows us to compute spill weights for
new registers created after the spill weight pass has run.

Also compute the allocation hint at the same time as the spill weight. This
allows us to use the spill weight as a cost metric for copies, and choose the
most profitable hint if there is more than one possibility.

The new hints provide a very small (< 0.1%) but universal code size improvement.
