[PATCH] testsuite: Fix up builtin-prefetch-1.c tests

[Xi Ruoyao]

How can you use "read-shared" as an identifier?  It's not allowed by all
C standard versions.

gcc/testsuite/ChangeLog:

        * gcc.c-torture/execute/builtin-prefetch-1.c (rws): Use
        "read_shared" instead of "read-shared" as the identifier for
        enum value.
        * gcc.dg/builtin-prefetch-1.c (rws): Likewise.

Bootstrapped and regtested on x86_64-linux-gnu.  The following test
failures are resolved:

Ok for trunk?
