[PATCH v2 0/1] MR10497: vbscript: Return specific error codes for unterminated block statements.

[Francis De Brabandere (＠francisdb)]

When a block statement reaches EOF without its closing keyword,
Windows returns a specific error code. Add error productions in the
bison grammar for four unterminated block types:

- If without End If (error 1014)
- While without Wend (error 1018)
- Do without Loop (error 1019)
- For/For Each without Next (error 1020)

Previously these all fell through to the generic E_FAIL path.
