c842fee0a4 [AutoDiff upstream] Add @transpose(of:) attribute. 
The `@transpose(of:)` attribute registers a function as a transpose of another
function. This patch adds the `@transpose(of:)` attribute definition, syntax,
parsing, and printing.

Resolves TF-827.

Todos:
- Type-checking (TF-830, TF-1060).
- Enable serialization (TF-838).
- Use module-qualified names instead of custom qualified name syntax/parsing
  (TF-1066).

63ec1cf5af Introduce a separate #filePath, remove -pound-file 
This makes the path behavior more first-class. The feature is now hidden behind an experimental flag, -enable-experimental-concise-pound-file.

5accda22b2 [AutoDiff upstream] Introduce @differentiable attribute to mark functions as differentiable. (#27506) 
This PR introduces `@differentiable` attribute to mark functions as differentiable. This PR only contains changes related to parsing the attribute. Type checking and other changes will be added in subsequent patches.

See https://github.com/apple/swift/pull/27506/files#diff-f3216f4188fd5ed34e1007e5a9c2490f for examples and tests for the new attribute.

1ebf2f2463 [gyb_syntax_support] Make node descriptions multi-line 
The node descriptions are printed as dedented multi-line strings when
the corresponding files are being generated in SwiftSyntax. To do this,
however, the strings need to be multi-line to begin with and not have
the line break escaped.

2509f50e45 Syntax: introduce a token kind for single quote to preserve round-trip printing of syntax tree 
For invalid code, lexer is forgiving enough to allow single quote '\'' as the starting point
of string literals. Later, parser assumes the string literals are always using double quote "\"", and passes
such knowledge to SwiftSyntax side, leading to the round-trip failure we observed in the radar.
This commit fixes the issue by introducing another token kind for single quote.
