gccrs: better handling of incorrect file loading in include_* builtin macros
When the load_file_bytes() fails to open the file, it emits an error but
returns an empty vector (as if the file is empty).
Instead, return a tl::optional nullopt in case of error and an empty
vector in case of an empty file.
fixes #2421
gcc/rust/ChangeLog:
* expand/rust-macro-builtins.cc
(load_file_bytes): Return a tl::optional.
(MacroBuiltin::include_byte_handler): Adjust and check file was
correctly opened.
(MacroBuiltin::include_str_handler): Likewise.
gcc/testsuite/ChangeLog:
* rust/compile/empty_file: New file.
* rust/compile/issue-2421_str.rs: New test.
