use MachineBasicBlocks.  To do this, we traverse the Machine CFG instead of
the LLVM CFG, which is also *MUCH* more efficient by having fewer levels of
indirections and mappings.

is only used by a cast, and the casted type is the same size as the original
allocation, it would eliminate the cast by folding it into the allocation.

Unfortunately, it was placing the new allocation instruction right before
the cast, which could pull (for example) alloca instructions into the body
of a function.  This turns statically allocatable allocas into expensive
dynamically allocated allocas, which is bad bad bad.

This fixes the problem by placing the new allocation instruction at the same
place the old one was, duh. :)

* Make contained ostream pointer, not reference
* Allow setting of that ostream via setStream()

class CachedWriter:
* setStream() in turn calls setStream() on the AssemblyWriter

llvm-svn: 13247

* Remove various print methods that called the Value* method, just have one that
  all subclasses of Value will use anyway.
* Remove template for printing constant references
* Add methods to print char* and strings
* setStream now sets the stream on the contained AssemblyWriter

llvm-svn: 13246

llvm-svn: 13243

llvm-svn: 13228

* Add Module accessor to AssemblyWriter

llvm-svn: 13227

* New feature: outputting a Type* as symbolic, controlled via the stream
  similarly to sending std::hex to change number format

In InsertFPRegKills(), just check the MachineBasicBlock for successors
instead of its corresponding BasicBlock.
