9e3d3abd93 Remove the assumption that FP's are either float or
double from some of the many places in the optimizers
it appears, and do something reasonable with x86
long double.
Make APInt::dump() public, remove newline, use it to
dump ConstantSDNode's.
Allow APFloats in FoldingSet.
Expand X86 backend handling of long doubles (conversions
to/from int, mostly).

43421b3dd7 Next round of APFloat changes.
Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double.  Remove
the ConstantFP double interfaces.
Use APFloat functions for constant folding arithmetic
and comparisons.
(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)

832254e1c2 Changes to support making the shift instructions be true BinaryOperators.
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.

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.

c2dfb8bb90 Make ConstantBool act like a 1 bit ConstantInt, in order to simplify client
code.  Patch contributed by Vladimir Prus.

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.

9b0a5ee5bb 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.
