eecfea4da6 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.

7fa6e666ec 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.

40bbeb5d07 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.

ca705fa31d 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.

e0fbb497ee - ConstantPointerRefs are now automatically removed from the module table

* Correctly delete TypeHandles in AsmParser.  In addition to not leaking

 * Check for errors in the AsmParser instead of hitting assertion failures
   deep in the code
 * Simplify the interface to the ConstantExpr class, removing unneccesary
   parameters to the ::get* methods.
 * Rename the 'getelementptr' version of ConstantExpr::get to
   ConstantExpr::getGetElementPtr

29ab9f8348 Added subclass ConstantExpr to represent expressions consructed from
constants using operators such as cast, getelementptr, add, shl, etc.
Note that a ConstantExpr can be of any type, so classof() in most
other subclasses (that discriminate by type) have to check that it
is also not a ConstantExpr.   This is why isConstantExpr() is needed.

10586abe9a Remove getStrValue method from Constant implementations. The AssemblyWriter
now knows how to write out a constant, not the constants themselves.  This is
fixed due to the move of the AsmWriter to the VMcore library.
