[PATCH] D71461: [LSAN] Increase stack space for guard-page.c test

When running the tests on a Ubuntu 18.04 machine this test is crashing for
me inside the runtime linker. My guess is that it is trying to save more
registers (possibly large vector ones) and the current stack space is not
sufficient.
