This ends up causing a bogus declaration mismatch error in the below testcase because the call to min in #1 gets expressed as a CALL_EXPR of ADDR_EXPR of FUNCTION_DECL, whereas the level-lowered call to min in #2 gets expressed instead as a CALL_EXPR of FUNCTION_DECL. This patch fixes this by stripping the spurious ADDR_EXPR appropriately. Thus the first call to min now also gets expressed as a CALL_EXPR of FUNCTION_DECL, matching the behavior before r12-6075-g2decd2cabe5a4f.
