bjh21 936b7f4cf8 Import the 32-bit version of SoftFloat 2a and separate it and the 64-bit
version into different directories.  Which version a given port uses is
controlled by the SOFTFLOAT_BITS make variable.  This is set to 64 (which
uses the same code we had before) by default.  32-bit platforms that don't
need extended precision support might get better performance by using 32.

Set the ARM port to use the 32-bit version of SoftFloat, since this is more
than a factor of two faster than the 64-bit version.  This should get the
floating-point performance back to what it was in 1.5.

This is a modified version of part of John Hauser's SoftFloat 2a package.
This version has been heavily modified to support its use with GCC to
implement built-in floating-point operations, but compiling
softfloat.c without SOFTFLOAT_FOR_GCC defined should get you the same
results as from the original.
