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.
