Reimplement tui_get_begin_asm_address

tui_get_begin_asm_address looks for the inferior's "main" to display
it.  I think this is incorrect in two ways.

First, it should probably instead use the user's most recent source
context, if one has been set.

Second, it uses a hard-coded list of "main" names, but gdb already has
a better approach to handling this.

This patch fixes both of these problems.
