Jacques Pienaar 644f722b36 [mlir-lsp] Report range of potential identifier starting at location of diagnostic
Currently the diagnostics reports the file:line:col, but some LSP
frontends require a non-empty range. Report either the range of an
identifier that starts at location, or a range of 1. Expose the id
location to range helper and reuse here.

River Riddle f8ac31314b Add a new AsmParserState class to capture detailed source information for .mlir files
This information isn't useful for general compilation, but is useful for building tools that process .mlir files. This class will be used in a followup to start building an LSP language server for MLIR.
