Remove la_get_string member
The la_get_string member of struct language_defn was intended to provide a way to fetch string data from a "string" object in a language-dependent way. However, it turned out that this was never needed, and was only ever implemented for C. This patch removes the language hook entirely. gdb/ChangeLog 2019-11-05 Tom Tromey <tom@tromey.com> * rust-lang.c (rust_language_defn): Update. * python/py-value.c (valpy_string): Call c_get_string. * p-lang.c (pascal_language_defn): Update. * opencl-lang.c (opencl_language_defn): Update. * objc-lang.c (objc_language_defn): Update. * m2-lang.c (m2_language_defn): Update. * language.c (unknown_language_defn, auto_language_defn): Update.
