fb11053815 Revise APIs for creating constantexpr GEPs to not require the use of
vectors.  This allows us to eliminate many temporary vectors, and their
associated malloc/free pairs.

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.

get(bool) be replaced by get(const Type*, uint64_t). This implements

They don't make sense for a signless type. Also, for isMaxValue and

it from the constant's type.

225e8dd2f5 Split SimpleConstantVal up into its components, so each Constant subclass gets
a different enum value.  This allows 'classof' for these to be really simple,
not needing to call getType() anymore.

This speeds up isa/dyncast/etc for constants, and also makes them smaller.
For example, the text section of a release build of InstCombine.cpp shrinks
from 230037 bytes to 216363 bytes, a 6% reduction.
