Also, copy tests for _mm_min_epi8, _mm_min_epu16, _mm_min_epi32,

from gcc/testsuite/gcc.target/i386.
sse4_1-pmaxsb.c and sse4_1-pminsb.c were modified from using
"char" types to "signed char" types, because the default is unsigned on
powerpc.
Where tested, do you want backports, etc...

I guess these are all integers, so we don't have to worry about
fast-math semantics. OK.

Please check/document -Wno-psabi. Otherwise the patch looks fine to
me. I won't hold you responsible for style issues in the x86 tests. :-)
Thanks!
