This function is the driver routine for replacement of temporary expressions
in the SSA->normal phase, operating on MAP.  If there are replaceable
expressions, a table is returned which maps SSA versions to the
expressions they should be replaced with.  A NULL_TREE indicates no
replacement should take place.  If there are no replacements at all,
NULL is returned by the function, otherwise an expression vector indexed
by SSA_NAME version numbers.
