Several tests assume that the first word after a thread ID in 'info threads' output is "Thread". However, several targets use "LWP" instead such as the FreeBSD and NetBSD native targets. The Linux native target also uses "LWP" if libthread_db is not being used. Targets that do not support threads use "process" as the first word via normal_pid_to_str. Add a tdlabel_re global variable as a regular-expression for a thread label in `info threads' that matches either "process", "Thread", or "LWP". Some other tests in the tree don't require a specific word, and some targets may use other first words (e.g. OpenBSD uses "thread" and Ravenscar threads use "Ravenscar Thread").
