313f8d3fcb [asm.js] Fix heap access validation of shift expressions. 
This makes sure that shift expressions (not wrapped in parentheses) can
appear as part of the index in a valid heap access expression. Only the
last operand of a sequence of shift expressions is taken into account
when validating the heap access.
