In looking at the failure of gcc.target/mips/ext-2.c, it looks like the
GCC compiler is now figuring out that it can use a 32 bit ext instruction
instead of a 64 bit dext instruction and that this is why the test
fails. Here is a patch to look for 'ext' or 'dext', OK to checkin?
It fixes the failure for me and I see no reason why GCC should not use
the ext instruction instead of dext in this case.
