Convert mn10300, MIPS and powerpc/rs6000 targets to use
BREAKPOINT_FROM_PC
Delete global variable memory_breakpoint_size.  Use BREAKPOINT_FROM_PC
instead.

+Use the program counter to determine the contents and size of a
+breakpoint instruction.  It returns a pointer to a string of bytes that
+encode a breakpoint instruction, stores the length of the string to
+*lenptr, and adjusts pc (if necessary) to point to the actual memory
+location where the breakpoint should be inserted.
+
+Although it is common to use a trap instruction for a breakpoint, it's
+not required; for instance, the bit pattern could be an invalid
+instruction.  The breakpoint must be no longer than the shortest
+instruction of the architecture.
+
+Replaces all the other BREAKPOINTs.
