internal/cmd/deadcode: a command to report dead code in Go programs

This CL adds a command to report functions that are unreachable
from the main functions of applications and tests.

It uses the Rapid Type Analysis (RTA) algorithm to
compute reachability, and reports all functions referenced
by the SSA representation that were not found to be
reachable, grouped by package and sorted by position.

Also, a basic integration test.
