[Bug c/39531] New: m68k gcc does not convert andil to bclr when compiled on a 64bit host

[radford at blackbean dot org]

The following function will use a bclr on a 32 bit host and a andil on a 64bit
host.

  int f(int x) { return x & 0x7fffffff; }

This is caused by a missing & 0xffffffff the expression

  exact_log2 (~ INTVAL (operands[2])))

in output_andsi3.
