  1. Sync to upstream/release/686 (#1948) 

    ## General
This week has been spent mostly on fixing bugs in incremental
autocomplete as well as making the new Type Solver more stable.

- Fixes a bug where registered "require" aliases were case-sensitive
instead of case-insensitive.
### New Type Solver
- Adjust literal sub typing logic to account for unreduced type
functions
- Implement a number of subtyping stack utilization improvements
- Emit a single error if an internal type escapes a module's interface
- Checked function errors in the New Non Strict warn about incorrect
argument use with one-indexed positions, e.g. `argument #1 was used
incorrectly` instead of `argument #0 was used incorrectly`.
- Improvements to type function reduction that let us progress further
while reducing
- Augment the generalization system to not emit duplicate constraints.
- Fix a bug where we didn't seal tables in modules that failed to
complete typechecking.

### Fragment Autocomplete
- Provide richer autocomplete suggestions inside of for loops
- Provide richer autocomplete suggestions inside of interpolated string
expressions
- Improve the quality of error messages when typing out interpolated
strings.

### Compiler
- Fixes REX encoding of extended byte registers for the x86 assembly
code generation.
- Fixes for table shape constant data encoding
