Chris Lattner d21cd809b6 Adjust to the changed StructType interface. In particular, getElementTypes() is gone.

Chris Lattner cfdf2419bc 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 90fb19ed2c 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 cbfd406541 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 ed468e37a1 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.
