Rust: Make 'tree'-level 'MAIN_NAME_P' work
'gcc/tree.h':
#define main_identifier_node global_trees[TI_MAIN_IDENTIFIER]
#define MAIN_NAME_P(NODE) \
(IDENTIFIER_NODE_CHECK (NODE) == main_identifier_node)
..., which is not initialized by default, but has to be set up by every front
end individually. 'MAIN_NAME_P' enables certain code optimizations, but is
especially also relevant for back ends that emit additional program entry setup
code for 'main'.
gcc/rust/
* backend/rust-compile-base.cc (HIRCompileBase::compile_function):
For 'main', initialize 'main_identifier_node'.
