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.)

This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported.

Make ParamAttrsList objects unique. You can no longer directly create or
destroy them but instead must go through the ParamAttrsList::get()
interface.

Rewrite the upgrade of GEP indices to be a little less obtuse. This fixes

For the short CALL/INVOKE syntax, the signedness of the result type is two
extractions away from the type argument because its a POINTER to function
type, not a function type.

Make Signedness information pervasive throughout all types and values.
There is no easy way to get around this. Because the GEP instruction can
index through an arbitrarily complex value structure, it is necessary to
keep track of signedness information throughout that structure. This change
makes Signedness a full class, capable of representing Signedness in
arbitrarily shaped types. The class is then used throughout llvm-upgrade to
track signedness and differentiate between globals, locals, and functions
based on their signedness.
For PR1243:
This patch also removes bogus warnings about renaming internal globals. It
now only emits such warnings when renaming non-internal globals because
they may affect linkage.

last entry stored in the map could be retrieved for a given integer type.
Propagating the sign information required an invasive change to ensure that
all ValueRef (ValID) instances get the right sign information as well. Also,
put in some assertions to ensure the RenameMap always gives us out the type
that is expected.
This fixes PR1256 and
