cmd/compile: allow directory specification for GOSSAFUNC output
This was useful for debugging failures occurring during make.bash.
The added flush also ensures that any hints in the GOSSAFUNC output
are flushed before fatal exit.
The environment variable GOSSADIR specifies where the SSA html debugging
files should be placed. To avoid collisions, each one is written into
the [package].[functionOrMethod].html, where [package] is the filepath
separator separated package name, function is the function name, and method
is either (*Type).Method, or Type.Method, as appropriate. Directories
are created as necessary to make this work.
