rs6000: Testcases for rl*i* 

These testcases test that we generate the expected code for all of the
rl*i* instructions, that is, rotate-and-mask and rotate-and-mask-insert
for immediate rotation counts.  All the testcases do rotate, shift left,
as well as shift right; if that results in an instruction that does not
exist the testcases generate a multiplication instead, so that we can
detect if this is handled properly.

Many 32-bit instructions zero-extend their result properly in 64-bit
mode, but the rs6000 port does not yet know.  These testcases test the
status quo, so they will need updating when ever we handle this.
