ec4a5672f8 Generalize FP constant shrinking optimization to apply to any vt
except ppc long double.  This allows us to shrink constant pool
entries for x86 long double constants, which in turn allows us to
use flds/fldl instead of fldt.

aa2acbbbf0 Improve comment, pass in the original VT so that we can shrink a long double constant
all the way to float, not stopping at double.

34bc178e4d Codegen support for i128 UINT_TO_FP. This just fixes a
bug in r47928 (Int64Ty is the correct type for the constant
pool entry here) and removes the asserts, now that the code
is capable of handling i128.

6fd599fa69 Add a target lowering hook to control whether it's worthwhile to compress fp constant.
For x86, if sse2 is available, it's not a good idea since cvtss2sd is slower than a movsd load and it prevents load folding. On x87, it's important to shrink fp constant since fldt is very expensive.

d86449e774 Some improvements related to the computation of heights, depths of SUnits.
The basic idea is that all these algorithms are computing the longest paths from the root node or to the exit node. Therefore the existing implementation that uses and iterative and potentially
exponential algorithm was changed to a well-known graph algorithm based on dynamic programming. It has a linear run-time.

405abffd5e Miscellaneous clean-ups based on Evan's feedback:
- Cleaned up how the prologue-epilogue inserter loops over the instructions.
- Instead of restarting the processing of an instruction if we remove an
  implicit kill, just update the end iterator and make sure that the iterator
  isn't incremented.
