[cmucl-imp] Snapshot 2014-08

[Raymond Toy]

First, in case you missed it, there was no 2014-07 snapshot. Nothing
really changed in that month so no snapshot was made.

Second, the 2014-08 snapshot has been tagged and binaries will be
uploaded soon.

Notable changes:

 * Updated to ASDF 3.1.3.
 * More consistent results for the special functions because all
   platforms now use fdlibm.
 * Consing for the trig functions is greatly reduced since we use
   fdlibm instead of a Lisp implementation.
 * Source location information has been added for
   DEFINE-CONDITION. (From Helmut Eller.)
 * The lisp binary  is now compiled to use SSE2 on x86 machines.
   CMUCL won't even start now if you do not have SSE2.
 * CLEAR-OUTPUT will now actually clear any pending output that has
   not been flushed.  Previously, CLEAR-OUTPUT did nothing.
 * For Gray streams, CLEAR-OUTPUT will clear output instead of calling
   STREAM-FORCE-OUTPUT.
 * A critical bug in KERNEL:DOUBLE-FLOAT-BITS on x86 has been
   fixed. In some situations, KERNEL:DOUBLE-FLOAT-BITS would cause a
   segfault.
