caaa49336b More ProfileInfo improvements. 
- Part of optimal static profiling patch sequence by Andreas Neustifter.

 - Store edge, block, and function information separately for each functions
   (instead of in one giant map).

 - Return frequencies as double instead of int, and use a sentinel value for
   missing information.

3fe14bf153 Check for !isa<Constant> instead of isa<Instruction>. This 
matches what the comment says, and it avoids spurious BitCast
instructions for Argument values.

cdc0654b3e Make SimplifyDemandedUseBits generate vector constants where 
appropriate.  Patch per report on llvmdev.  No testcase because the 
original report didn't come with a testcase, and I can't come up with a case
that actually fails.

metadata related, which I'm waiting on to avoid conflicting with Devang.

fe09b2098a Twines: Don't allow implicit conversion from integers, this is too tricky.

7f93dc8345 Switch obvious clients to Twine instead of utostr (when they were already using 
a Twine, e.g., for names).
 - I am a little ambivalent about this; we don't want the string conversion of
   utostr, but using overload '+' mixed with string and integer arguments is
   sketchy. On the other hand, this particular usage is something of an idiom.
