arbitrary range of bits embedded in the middle of another bignum.
This kind of operation is desirable in many cases of software
floating point, e.g. converting bignum integers to floating point
numbers of fixed precision (you want to extract the precision most
significant bits).

Elsewhere, add an assertion, and exit the shift functions early if
the shift count is zero.

convertFromZeroExtendedInteger can be simplified as it doesn't need
to make a copy of the source bignum.

It used to modify its argument in-place.

This interface is saner and the implementation more efficient.  It will
be needed for decimal->binary conversion.

modified the function to expect zero-extended input.  Make this
assumption explicit in the function name.

bit width instead of number of words allocated, which
makes it actually work for int->APF conversions.
Adjust callers.  Add const to one of the APInt constructors
to prevent surprising match when called with const

Make APInt::dump() public, remove newline, use it to
dump ConstantSDNode's.
Allow APFloats in FoldingSet.
Expand X86 backend handling of long doubles (conversions
