Log Message:
1.0.4.55: Optimized REPLACE and UB*-BASH-COPY routines

	* Expand simple cases of UB*-BASH-COPY inline to avoid full call
	  overhead and generate better code generally;
	* Handle more cases of REPLACE; we now optimize REPLACE on all
	  simple specialized array types (only element types <= n-word-bits
	  are handled generally, though);
	* Use a single COPY-SEQ and SUBSEQ transform rather than one per
	  specialized array type; generate inline copies for these too
	  when possible;
	* Tests;
	* Backend cleanup: introduce a FIND-SAETP to eliminate duplicate code;
	* Backend cleanup: change %{SET-,}VECTOR-RAW-BITS on x86 to use
	  the *-WITH-OFFSET machinery.

   * optimization: GET-INTERNAL-REAL-TIME has been optimized on POSIX
     platforms. (thanks to James Anderson for the optimization hint)
+  * optimization: REPLACE, SUBSEQ, and COPY-SEQ are now optimized in

   * enhancement: XREF information is now collected to references made
     to global variables using SYMBOL-VALUE with a constant argument.
   * bug fix: dead unbound variable references now signal an error.
