Make APInt::dump() public, remove newline, use it to

Expand X86 backend handling of long doubles (conversions
to/from int, mostly).

llvm-svn: 41758

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.)
