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).

(http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20070910/053370.html). It's
causing SPASS to fail.

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.)

Added default parameters to GetElementPtrInstr constructor call.  Visual Studio 2k5 was getting confused and was unable to compile it.  Suspected compiler error.

GLIBCXX_DEBUG issues.

Move exit condition and exit branch from exiting block into loop header and dominator info. This avoid execution of dead iteration. Loop is already filter in the beginning such that this change is safe.

While calculating upper loop bound for first loop and lower loop bound for second loop, take care of edge cases.

Fix regression that I caused yesterday night while adding logic to select appropriate split condition branch.

condition predicate is GT or GE then execute false branch first.

"True Loop" and "False Loop" naming terminology to refer two loops
after loop cloning is confusing. Instead just use A_Loop and B_Loop.
