a test used to pass and now fails.
It looks like you have to update it to take into account the new, better code.

This patch is designed to improve code generation for "and" instructions with
certain immediate operands.
For the following test case:
int f2(int x)
{
x &= 0x0ff8;
x &= 0xff001fff;
return x;
}
the trunk aarch64 compiler generates:
mov w1, 8184
movkw1, 0xf00, lsl 16
and
