I would like to modify gcc.target/aarch64/long_branch_1.c to no longer
look for an Ltb label.  After a patch to c-typeck.c to add a predict
statement to GOTO statements, GCC no longer generates one of the types
of long branch that this test is checking for.

I tried modifying the test and creating a new test to generate this label
but was unsucessful, I also added in an abort statement that would trigger
when GCC tried to generate this label and then ran a bootstrap GCC build
and a full testsuite run.  The abort never triggered. There may still
be some way to generate this label but I don't think it is worth the time
to find it and so I would like to just remove the check so that the
testcase no longer fails.

OK for checkin?  Tested on aarch64.
