Use std::string and unique_xmalloc_ptr in compile/ code
Change various things in the compile/ code to use std::string or unique_xmalloc_ptr as appropriate. This allows the removal of some cleanups. ChangeLog 2017-09-03 Tom Tromey <tom@tromey.com> * compile/compile.c (compile_register_name_mangled): Return std::string. * compile/compile-loc2c.c (pushf_register_address): Update. (pushf_register): Update. * compile/compile-c-types.c (convert_array): Update. * compile/compile-c-symbols.c (generate_vla_size): Update. (error_symbol_once): Use a gdb::unique_xmalloc_ptr. (symbol_substitution_name): Return a gdb::unique_xmalloc_ptr. (convert_one_symbol): Update. (generate_c_for_for_one_variable): Update. * compile/compile-c-support.c (c_get_range_decl_name): Return a std::string. (generate_register_struct): Update. * compile/compile-internal.h (c_get_range_decl_name): Return a std::string. (compile_register_name_mangled): Return std::string.
