proc,locspec: support setting breakpoints by func name on generic funcs (#2745)
* proc,locspec: support setting breakpoints by func name on generic funcs

Changes proc.Function to parse function names correctly when they
contain instantiation lists and locspec to match generic functions.

* vendor: update golang.org/x/tools

The old version of golang.org/x/tools is incompatible with the new
iexport format.
