Close #2076: add analog as potential AMS-dialect word in parser according to #2076 (comment)

[matlupi]

Added testcase for #2076

[hzeller]

This creates a shift-reduce conflict, so the grammar probably has to be massaged more.

Any hint on where to try to investigate it?

[hzeller]

This is essentially an ambiguity in the grammar where the parser might not be able to decide. One problem is, that now TK_analog is part of multiple rules, and these rules might both be matched. Next step would probably to check the original location of where Tk_analog and see if it can be replaced with KeywordIdentifier and still keep the semantics.

There are probably also a bunch of resources 'on the net' for shift/reduce conflicts resources.

[hzeller]

There should be a file generated in bazel-bin/verilog/parser/verilog.output which might be helpful

[fangism]

The verilog.output file is a "human-readable" state machine of the parser, which explains how conflicting states are reached.
