a3cf123e86 strength reduce a ton of type equality tests to check the typeid (Through 
the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

01dae858b6 eliminate the "Value" printing methods that print to a std::ostream. 
This required converting a bunch of stuff off DOUT and other cleanups.

1dc40e205b Move a few more APIs back to 2.5 forms. The only remaining ones left to change back are 
metadata related, which I'm waiting on to avoid conflicting with Devang.

81f704c26a Twines: Don't allow implicit conversion from integers, this is too tricky.

4d07efb3c4 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.

251177c96e Initial update to VMCore to use Twines for string arguments. 
- The only meat here is in Value.{h,cpp} the rest is essential 'const
   std::string &' -> 'const Twine &'.

f955a6ef49 llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

ae8a3ff177 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

2b0edc3327 PR4286: Make RewriteLoadUserOfWholeAlloca and 
RewriteStoreUserOfWholeAlloca deal with tail padding because 
isSafeUseOfBitCastedAllocation expects them to.  Otherwise, we crash 
trying to erase the bitcast.

f7af13b2d4 Rename PaddedSize to AllocSize, in the hope that this 
will make it more obvious what it represents, and stop
it being confused with the StoreSize.

0fd5aea274 fix RewriteStoreUserOfWholeAlloca to use the correct type size 
method, fixing a crash on PR4146.  While the store will 
ultimately overwrite the "padded size" number of bits in memory,
the stored value may be a subset of this size.  This function
only wants to handle the case where all bits are stored.
