[gdb/symtab] Support DW_AT_main_subprogram with -readnow.
DW_AT_main_subprogram is supported in normal mode in read_partial_die, but not in -readnow mode. Fix this by adding support for DW_AT_main_subprogram in read_func_scope. Tested on x86_64-linux with native and RFC target board readnow ( https://sourceware.org/ml/gdb-patches/2019-05/msg00073.html ). gdb/ChangeLog: 2019-06-10 Tom de Vries <tdevries@suse.de> PR symtab/16264 PR symtab/24517 * dwarf2read.c (read_func_scope): Handle DW_AT_main_subprogram.
