Prior to this, we never update the compiler options stored for scripts. This means that as you add #r or #load the compilation options aren't updated.

This PR updates the options in the semantic analysis phase. We can't update them on every request for options because it is too expensive.

This fixes some aspects of #1808 but the underlying problem of not reacting to file update events in dependencies is not fixed.

This implements signature help (method overload tips and parameter info). #1767. Also fixes #1856

This is mostly just wiring up the necessary things and copying across some of the nitty-gritty detail from the old language service. Some additional information was propagated such as HasParamArrayArg.

Fixes #1821

Incremental colorization was not being effective on changing files for a number of reasons
•Data cache was keyed by source text rather than document ID
•We were writing None entries right through to end-of-file even when we could stop earlier
•We weren't checking that start-of-line indexes and lex states were still the same when reusing entries
•Tokenizers getting recreated for each line - we can cache these as well.

I've tried the PR out on large files and it works much more efficiently.

Also a fix to make  ShouldTriggerCompletionAux  faster in the common case where not pressing  . 

This also fixes glyphs: #1806. Public/private/protected is not yet propagated to the glyph but this gives us feature parity with VS2015
