Fix for Coverity bug 1212416

Coverity correctly pointed out that returnInfoGetMemberRef had an INT_FATAL call
and a return statement that would never be reached, as the if/else branch above
it had a return statement at the close of both branches.  I have removed these
lines and tested this over std.
Fix Coverity issues 1212401 and 1212402

In stmt.cpp, Coverity noticed that there were null checks for two variables that
had already been checked.  While what it complained about was the possibility
that the later dereference was to a null pointer, it was fair to point out that
the variables did not need to be checked again.  I believe that removing the
additional check will resolve these issues.
Check for grepstdchdrs script before calling it.

It is possible that CHPL_DEVELOPER is defined in a release tarball environment,
which does not have util/devel/grepstdchdrs script.
Fix Coverity issue 1212355

Coverity had informed us that a variable could be null at the point where it
was being dereferenced during code generation.  This inserts a minor check to
make sure that is not the case.  Tested over std.
Fix BUILD_VERSION value in non-repo, non-development environment.

When the tarball is unpacked, value set in BUILD_VERSION should default to "0"
(including quotes). Previously, it was setting the value to literal 0, which
was appropriate in the SVN world.
