Chris Lattner 6e415c06c2 Add support for select constant expressions. Use reserve a bit more to avoid 
memory wasteage.

Chris Lattner 9fba3da879 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.

Chris Lattner 015e821279 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.

Chris Lattner ac80ea4970 Second half of a fix for PR218 & test/Regression/Assembler/2004-02-01-NegativeZero.llx. 
Basically we store floating point values as their integral components, instead of relying
on the semantics of floating point < to differentiate between values.  This is likely to
make the map search be faster anyway.

Chris Lattner 241ed4c500 Fix a problem brian ran into with the bytecode reader asserting. It turns 
out that the problem was actually the writer writing out a 'null' value
because it didn't normalize it.  This fixes:

Chris Lattner 5a945e3616 Rename ConstantHandling.* -> ConstantFolding.* 
Move a bunch of (now) private stuff from ConstantFolding.h into
ConstantFolding.cpp.

This _finally_ gets us to a place where we have a sane constant folder.  The
rules are:

1. LLVM clients now use ConstantExpr::get* methods to fold constants.  If they
   cannot be folded, a constantexpr is created, so these methods always return
   valid Constant*'s.
2. The implementation of ConstantExpr::get* uses the functions exposed by
   ConstantFolding.h to try to fold constants.  If they cannot be folded,
   they should return a null pointer.
3. The implementation of ConstantFolding can do whatever it wants, and only
   has one client (Constants.cpp)

This cuts down on the wierd dependencies, and eliminates the two interfaces.
The old constanthandling interface was especially bad for clients to use
because almost none of them took the failure condition into consideration,
thus leading to obscure problems.

Chris Lattner b50d135710 Type tables are now AbstractTypeUsers. This allows them to merge together 
constants as necessary due to type resolution.  With this change, the
following spec benchmarks now link: 176.gcc, 177.mesa, 252.eon,
253.perlbmk, & 300.twolf.  IOW, all SPEC INT and FP benchmarks now link.

were never merged together, now they are.

Chris Lattner 0c6e0b9042 - ConstantPointerRefs are now automatically removed from the module table

 * 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.

Vikram S. Adve 4e537b27d8 Added subclass ConstantExpr to represent expressions consructed from

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.
