Function get_stdlib_modules_for_mode

crates/hll-to-ir/src/stdlib.rs:14–35

Return the stdlib as a list of (`module_name`, source) tuples for the given mode. This makes it possible to compile each HLL file independently so that `.ir`, `.s` and `.o` artifacts exist per original source file instead of concatenating everything into one big bundle.
