It makes sense to use what other targets do and run all the VAX test
cases over all the usual optimization levels, so make `vax.exp' use our
`gcc-dg-runtest' rather than the generic `dg-runtest' test driver.
This breaks `pr56875.c' however, which is optimized away at levels above
`-O0' as a result of how it has been written for calculations to make no
effect:
FAIL: gcc.target/vax/pr56875.c -O1 scan-assembler ashq
.*,\\$0xffffffffffffffff,
FAIL: gcc.target/vax/pr56875.c -O2 scan-assembler ashq
.*,\\$0xffffffffffffffff,
FAIL: gcc.target/vax/pr56875.c -O3 -g scan-assembler ashq
.*,\\$0xffffffffffffffff,
FAIL: gcc.target/vax/pr56875.c -Os scan-assembler ashq
.*,\\$0xffffffffffffffff,
FAIL: gcc.target/vax/pr56875.c -O2 -flto -fno-use-linker-plugin

FAIL: gcc.target/vax/pr56875.c -O2 -flto -fuse-linker-plugin
-fno-fat-lto-objects scan-assembler ashq .*,\\$0xffffffffffffffff,
Rather than keeping it at `-O0' update the test case for its code to do
make effect while retaining its sense. Also reformat it according to
our requirements.
gcc/testsuite/
* gcc.target/vax/vax.exp: Use `gcc-dg-runtest' rather than
`dg-runtest'.
* gcc.target/vax/pr56875.c (dg-options): Make empty.
(a): Rewrite for calculations to make effect. Reformat.
