changes in sbcl-1.3.10 relative to sbcl-1.3.9:
* enhancement: more compact low-level error signaling code
* enhancement: more compact encoding of cross-reference information
* optimization: faster out of line fixnum-float comparisons.
* optimization: filling a known simple-vector with a constant value
is about as fast in unoptimized code as in code compiled with (SPEED 3),
and the x86-64 implementation is able to use SSE instructions.
* bug fix: correctly handle the case of a non-local exit within a function
terminating the extent of dynamic-extent functions and variables in the
presence of multiple-values (lp#1563127)
* bug fix: restore builds on the latest OSX with the latest Xcode
(lp#1470996)
