I hope this won't be too controversial.

This patch provides a way to force a function to have certain attributes from the command line. This can be useful when debugging or doing workload exploration, where manually editing IR is tedious or not possible (due to build systems etc).

The syntax is -force-attribute=function_name:attribute_name

For example, a function can be force-inlined using `-force-attribute myfunc:alwaysinline`
