PEI is now responsible for adding MaxCallFrameSize to frame size and align the stack. Each target can further adjust the frame size if necessary.

these alignment amounts to align scalars when we can.  Patch by Scott Michel!

Last check-in was bogus. There is no need to align the stack if the function is a leaf function (and without alloca).

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.
