When running the testsuite on boards that can't report an error status
DejaGNU uses a special wrapper to print the exit code on stdout and
parses stdout to find whether an execution failed or passed.

In testcases that use "freopen (..., ..., stdout)" this special line is
printed to the alternate location described in the freopen call and
DejaGNU can't find the error code.

This results in DejaGNU using a default return status of 2 and the test
failing.

This patch skips the two testcases that use freopen on stdout when
testing a board that requires this wrapper.


Testing done by running these two tests on arm-none-eabi cross build and
observing that they are unsupported.

Fixes rXsbg_mode_sXl test failures.

Combine used to give us

            (const_int 2 [0x2]))

but now we get

    (ior:SI (subreg:SI (zero_extract:DI (reg:DI 69)
                (const_int 32 [0x20])

        (subreg:SI (reg:DI 68) 4)))

with an extra subreg, which appears because pseudos, unlike hard
registers, can be accessed only using their natural mode.

This patch adds a special case for that.  Also, it performs r*sbg
bit index computations during gcc run, so that expectations do not
depend on which concrete pattern was matched.

GCN vector sizes range between 64 and 512 bytes, none of which have
correspondingly sized integer modes.  This breaks a number of assumptions
throughout the compiler, but I don't really want to create modes just for this
purpose.

Instead, this patch fixes up the cases that I've found, so far, such that the
compiler tries something else, or fails to optimize, rather than just ICE.
