Research direction

Start by investigating rustc's handling of code-generation and stack-related command-line options, then compare the requested behavior with GCC's -mpreferred-stack-boundary and Clang's -mstack-alignment documentation. The issue names no files or tests; done would mean rustc supports the requested -Cstack-alignment and -Cpreferred-stack-boundary options with defined behavior.
