re PR c/83844 (ICE with warn_if_not_aligned attribute)
PR c/83844
* stor-layout.c (handle_warn_if_not_align): Use byte_position and
multiple_of_p instead of unchecked tree_to_uhwi and UHWI check.
If off is not INTEGER_CST, issue a may not be aligned warning
rather than isn't aligned. Use isn%'t rather than isn't.
* fold-const.c (multiple_of_p) <case BIT_AND_EXPR>: Don't fall through
into MULT_EXPR.
<case MULT_EXPR>: Improve the case when bottom and one of the
MULT_EXPR operands are INTEGER_CSTs and bottom is multiple of that
operand, in that case check if the other operand is multiple of
bottom divided by the INTEGER_CST operand.
* gcc.dg/pr83844.c: New test.
