1.0.19.14: Immediate SAP bug fix & grab bag of small changes
* SAPs can't actually be emitted as immediates. Only a problem now that
constants are treated more cleverly.
Fixes the "#.(SB-SYS:INT-SAP #X00000000) fell through ETYPECASE expression"
bug associated with CFFI's NULL-POINTER. Reported by Ingo Bormuth on
sbcl-devel, and by several others on #lisp.
* EAs can still only fit 32 bit displacements on x86-64.
* Make SAP-INT foldable, thus improving code generation for expressions
like (sap= +null-pointer+ sap).
* SAPs can't actually be emitted as immediates. Only a problem now that
