536a465ceb Change the signature of replaceUsesOfWithOnConstant to take a Use* and not
take the bool.  The bool is always true dynamically.

92616caa1a 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.

9b289130f7 Eliminate the explicit opcode field in ConstantExpr, using the SubclassData
field to hold it instead.  This shrinks memory usage for 176.gcc from
57628728 to 57598144 bytes, a small reduction of about 30K.

63ba63bb56 Allow creation of GEP constantexprs with a vector of value* operands as
well as a vector of constant*'s.  It turns out that this is more efficient
and all of the clients want to do that, so we should cater to them.

363cd9e4b8 Add a new ConstantAggregateZero class, to fix PR239. This makes zero
initializers for constant structs and arrays take constant space, instead of
space proportinal to the number of elements.  This reduces the memory usage of
the LLVM compiler by hundreds of megabytes when compiling some nasty SPEC95
benchmarks.

0f819b9523 ConstantArray::get and ConstantStruct::get now just return pointers to
'Constant', instead of specific subclass pointers.  In the future, these will
return an instance of ConstantAggregateZero if all of the inputs are zeros.

599ab961c4 Add new ConstantArray::isString(), as the conditions for using getString()
are complex enough to check that it should be a seperate method.

While I'm here, improve ConstantArray::getNullValue a bit, though the
FIXME is still quite valid.
