c4558fde76 Unbreak VC++ build. Do not use identifiers starting with _ as they are reserved and 
can collide with system defined names.  Windows defines _BB, for example.

dfb22c3521 redesign the primary datastructure used by mem2reg to eliminate an 
std::map of std::vector's (ouch!).  This speeds up mem2reg by 10% on 176.gcc.

d3874049a5 With the last change, we no longer need both directions of mapping from 
BBNumbers.  Instead of using a bi-directional mapping, just use a single
densemap.  This speeds up mem2reg on 176.gcc by 8%, from  1.3489 to
1.2485s.

ef9b9a7939 For PR411: 
This patch replaces the SymbolTable class with ValueSymbolTable which does
not support types planes. This means that all symbol names in LLVM must now
be unique. The patch addresses the necessary changes to deal with this and
removes code no longer needed as a result. This completes the bulk of the
changes for this PR. Some cleanup patches will follow.

9fa038dc21 Change constant folding APIs to take an optional TargetData, and change 
ConstantFoldInstOperands/ConstantFoldCall to take a pointer to an array

This allows us to get rid of some special case gross code that was there
to avoid the cost of constructing a vector.

c10305743c For PR1043: 
This is the final patch for this PR. It implements some minor cleanup
in the use of IntegerType, to wit:
1. Type::getIntegerTypeMask -> IntegerType::getBitMask
2. Type::Int*Ty changed to IntegerType* from Type*
3. ConstantInt::getType() returns IntegerType* now, not Type*

This also fixes PR1120.

Patch by Sheng Zhou.

42a7551725 rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger. 
rename Type::getIntegralTypeMask to Type::getIntegerTypeMask.

This makes naming much more consistent.  For example, there are now no longer any
instances of IntegerType that are not considered isInteger! :)
