commit 082b9140d953b9e6a78271384ec48ff5d0ba8fad
Author: Simon Marchi <simon.marchi@polymtl.ca>

Make tdesc_type::name an std::string
This patch makes tdesc_type::name an std::string. This way, we don't
need to free it manually in ~tdesc_type. I think the comment on top of
name is not correct, the string is always malloc'ed.
gdb/ChangeLog:
* target-descriptions.c (struct tdesc_type) <name>: Change type
to std::string.
<~tdesc_type>: Don't manually free name.
<operator==>: Adjust.
(tdesc_named_type): Adjust.
(tdesc_find_type): Adjust.
(tdesc_gdb_type): Adjust.
(class print_c_tdesc) <visit>: Adjust.
