This patch adds support for the DW_AT_trampoline attribute whose value
is a boolean. Which is a "generic trampoline". Stepping into a generic
trampoline by default will step through the function, checking
at every branch, until we stop in a function which makes sense to stop
at (a function with debug info, which isn't a trampoline, for example).
