[committed] Fix copy&paste bug in function-tests.c

[David Malcolm]

I made a copy&paste error when writing
selftest::verify_three_block_rtl_cfg, forgetting to update the
basic block ptr when asserting the value of "flags".

Fixed thusly.

Successfully bootstrapped&regrtested on x86_64-pc-linux-gnu.
Verified -fself-test of stage1 on powerpc-ibm-aix7.1.3.0.

Committed to trunk (r238470) under the "obvious" rule.

gcc/ChangeLog:
        * function-tests.c (selftest::verify_three_block_rtl_cfg): Verify
        the flags of the exit block and bb2, not just the entry block.
