[PATCH] Turn some compile-time tests into run-time tests

[Patrick Palka <patrick@parcs.ath.cx>]

I ran the command

  git grep -l "dg-do compile" | xargs grep -l __builtin_abort | xargs grep -lw main

to find tests marked as compile-time tests that likely ought to instead
be marked as run-time tests, by the rationale that they use
__builtin_abort and they also define main().  (I also then confirmed that they
compile, link and run cleanly on my machine.)

After this patch, the remaining test files reported by the above command
are:

  These do not define all the functions they use:
    gcc/testsuite/g++.dg/ipa/devirt-41.C
    gcc/testsuite/g++.dg/ipa/devirt-44.C
    gcc/testsuite/g++.dg/ipa/devirt-45.C
    gcc/testsuite/gcc.target/i386/pr55672.c

  These are non-x86 tests so I can't confirm that they run cleanly:
    gcc/testsuite/gcc.target/arm/pr58041.c
    gcc/testsuite/gcc.target/powerpc/pr35907.c
    gcc/testsuite/gcc.target/s390/dwarfregtable-1.c
    gcc/testsuite/gcc.target/s390/dwarfregtable-2.c
    gcc/testsuite/gcc.target/s390/dwarfregtable-3.c

  These use dg-error:
    libstdc++-v3/testsuite/20_util/forward/c_neg.cc
    libstdc++-v3/testsuite/20_util/forward/f_neg.cc

Bootstrapped and regtested on x86_64-pc-linux-gnu, does this look OK to
commit?  Does anyone have another heuristic one can use to help find
these kinds of typos?
