Initial commit of SoftFloat 2a import. This should provide a sensible mostly-MI floating-point implementation for use by gcc -msoft-float. It's currently only used by arm26, but should be usable by other ports without too much hacking, assuming doubles and u_int64_ts are passed and returned the same way, and FP formats are IEEEish.

Each of the following `typedef's defines the most convenient type that holds
integers of at least as many bits as specified. For example, `uint8' should
be the most convenient type that can hold unsigned integers of as many as
8 bits. The `flag' type must be able to hold either a 0 or 1. For most
implementations of C, `flag', `uint8', and `int8' should all be `typedef'ed
to the same as `int'.

The `LIT64' macro takes as its argument a textual integer literal and
if necessary ``marks'' the literal as having a 64-bit integer type.
For example, the GNU C Compiler (`gcc') requires that 64-bit literals be
appended with the letters `LL' standing for `long long', which is `gcc's
name for the 64-bit integer type. Some compilers may allow `LIT64' to be
defined as the identity macro: `#define LIT64( a ) a'.
