73cece2803 [libSyntax] Make SyntaxFactory methods instance methods 
This saves us from passing in the SyntaxArena every time a new node is
created.

9ff88b2839 [libSyntax] Fix SwiftSyntaxTests broken due to change SyntaxFactory API 
This fixes the SwiftSyntaxTests that were broken because the
SyntaxFactory API now requires an Arena in which the nodes should be
created.

3612cd3d72 [utils/gyb_syntax_support] Add collection_element_name for when specifying a Child

1015a6024d Syntax: use child name instead of type name for gyb-generated functions 
ParsedSyntaxBuilder has a convenient function to add member to a syntax-collection
child. The function name uses the type name of the collection's members,
which can lead to name collision. This patch renames it.

e07c00c652 Syntax: correct implementation for removing 
`llvm::ArrayRef<T>` does not define `erase`.  However, since the intent
here is to remove the last n elements, we can use `drop_back` instead.
Furthermore, replace the direct use of `Layout` with `getLayout()`.
This was identified by gcc 8.2.

1b3baf908f [incrParse] Add error nodes to the end of a CodeBlockItem 
Creating a new CodeBlockItem meant that when doing an edit in the error
nodes, the prefix gets reused and thus the code is parsed as invalid

057254dbc1 [Syntax] Bump allocate and cache/reuse RawSyntax 
Introduced SyntaxArena for managing memory and cache.

SyntaxArena holds BumpPtrAllocator as a allocation storage.
RawSyntax is now able to be constructed with normal heap allocation, or
by SyntaxArena. RawSyntax has ManualMemory flag which indicates it's managed by
SyntaxArena. If the flag is true, its Retain()/Release() is no-op thus it's
never destructed by IntrusiveRefCntPtr.
This speedups the memory allocation for RawSyntax.

Also, in Syntax parsing, "token" RawSyntax is reused if:
a) It's not string literal with >16 length; and
b) It doesn't contain random text trivia (e.g. comment).
This reduces the overall allocation cost.
