gdb/doc: Update 'frame' command documentation.

The documentation for the 'frame' command has gotten a little out of
date, it still mentions architecturally specific details that are no
longer relevant.

This commit removes the old details that no longer apply, and tries to
expand the existing text a little to make the usage clearer for some
cases.

gdb/doc/ChangeLog:

	* gdb.texinfo (Selection): Update documentation for 'frame'
	command.

Select the frame at address @var{stack-addr}. This is useful mainly if the
chaining of stack frames has been damaged by a bug, making it
impossible for @value{GDBN} to assign numbers properly to all frames. In
addition, this can be useful when your program has multiple stacks and
switches between them.
On the SPARC architecture, @code{frame} needs two addresses to
select an arbitrary frame: a frame pointer and a stack pointer.
On the @acronym{MIPS} and Alpha architecture, it needs two addresses: a stack
pointer and a program counter.
On the 29k architecture, it needs three addresses: a register stack
pointer, a program counter, and a memory stack pointer.
switches between them. The optional @var{pc-addr} can also be given to
specify the value of PC for the stack frame.
