126.96.36.199: better reporting for failure to stack allocate
* If the LVAR has no uses left, it is not good for DX.
* When flushing the destination of a DX lvar, note that its uses will
not be stack allocated.
* Pull out the failure to stack allocate reporting into
NOTE-NO-STACK-ALLOCATION, relax the filter to allow complaints
about non-constant REFs, and omit notes for flushed and flushable
combinations. TODO: the compiler should know about non-consing
functions, so that it can avoid inane notes like "could not stack
allocate the result of (CAR X)" should someone declare that DX.
* Muffle compiler notes from WITH-PINNED-OBJECTS, since our paranoid
use of DX-LET there is liable to cause lots of confusing "unable to
stack allocate" notes.

* optimization: more efficient type-checks for FIXNUMs when the value
is known to be a signed word on x86 and x86-64.
+ * improvement: failure to provide requested stack allocation compiler notes
+ provided in all cases (requested stack allocation not happening without a
+ note being issued is now considered a bug.)
* bug fix: on 64 bit platforms FILL worked incorrectly on arrays with
upgraded element type (COMPLEX SINGLE-FLOAT), regression from 188.8.131.52.
