[SyntaxTree] Extend the syntax tree dump

[eduucaldas]

Summary

Functional changes in the dump:

• Surround Leaf tokens with '
• Append Node dumps with NodeRole information, except for unknown roles

Non-functional changes:

• ::dumpTokens(llvm::raw_ostream, ArrayRef<syntax::Token>, const SourceManager &SM) always received as parameter a syntax::Token * pointing to Leaf::token(). Changed the function to dumpLeaf(llvm::raw_ostream, syntax::Leaf *, const SourceManager&)
• dumpTree acted on a Node, rename to dumpNode
• use SourceManager in parameters for dump instead of Arena

TODO:
Adapt all the tree dumps in TreeTest.cpp to this new format.

[eduucaldas]

Rollback strOfLeaf

[gribozavr2]

clang/lib/Tooling/Syntax/Tree.cpp

147–148

Maybe the marks should be moved after the primary identifier of the node, WDYT? That would be more consistent with AST dump: first the node kind, then all its info.

[eduucaldas]

Answer comment.

Please suggest more descriptive markers.
Options I thought of:
I -> unmodifiable
M -> not backed by source code / synthesized

[eduucaldas]

Adapt Statement tests to new testing infrastructure

[eduucaldas]

clang/lib/Tooling/Syntax/Tree.cpp

147–148

I agree

clang/unittests/Tooling/Syntax/BuildTreeTest.cpp

106–110

I just noticed that we didn't yet use annotations on statement tests.
I think that might help a bit, should I do a quick patch for adding those?

[gribozavr2]

Output format LGTM!

clang/lib/Tooling/Syntax/Tree.cpp

160

169–172

205–208

clang/unittests/Tooling/Syntax/BuildTreeTest.cpp

106–110

Yes, that's a good idea!

Update tests to dump role

• Nits
