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.

For PR950:
...
Three changes:
1. Convert signed integer types to signless versions.
2. Implement the @sext and @zext parameter attributes. Previously the
type of an function parameter was used to determine whether it should
be sign extended or zero extended before the call. This information is
now communicated via the function type's parameter attributes.
3. The interface to LowerCallTo had to be changed in order to accommodate
the parameter attribute information. Although it would have been
convenient to pass in the FunctionType itself, there isn't always one
present in the caller. Consequently, a signedness indication for the
result type and for each parameter was provided for in the interface
to this method. All implementations were changed to make the adjustment
necessary.
