ef0942c69c Add a convenience API SourceManager::addMemBufferCopy() to simplify adding a
buffer in case the client does not need a pointer to the buffer.

f232267f23 Replace llvm::OwningPtr with std::unique_ptr
It looks like llvm::OwningPtr is going to be removed soon.

b71d4c5a2c SourceManager: emphasize that some APIs accept only valid SourceLocations
Adding these asserts would help debugging.  Without the asserts it would fail
anyway, but in a more obscure place, usually with a null pointer dereference.

34df7b494e Comment parsing: recognize documentation and non-documentation comments, merge
consecutive documentation comments and form 'RawComment's.

ecd798b9fd Comment parsing: attaching comments to declarations
We can attach comments to declarations.  Right now we only support comments
that precede the declarations (trailing comments will be supported later).

The implementation approach is different from one we have in Clang.  In Swift
the Lexer attaches the comments to the next token, and parser checks if
comments are present on the first token of the declaration.  This is much
cleaner, and faster than Clang's approach (where we perform a binary search on
source locations and do ad-hoc fixups afterwards).

The comment <-> decl correspondence is modeled as "virtual" attributes that can
not be spelled in the source.  These attributes are not serialized at the
moment -- this will be implemented later.

6fb1dce5c1 [Frontend] When setting up the buffers for a CompilerInstance, allow a memory buffer to
provide the contents of a filename, based on its buffer identifier.

44d46de7c9 Use swift::SourceManager's addNewSourceBuffer() instead of llvm::SourceMgr's AddNewSourceBuffer().
Also remove the SourceLoc parameter from addNewSourceBuffer(). In llvm::SourceMgr
it is used to indicate textual inclusion, which we don't have in swift.

5db368ce7b [Lexer] Introduce Lexer::getLocForStartOfToken() that returns the location at the start of the token that a given offset points to.

70f2b64ad9 Add CharSourceRange -- a half-open character range, which will be used in IDE
integration

Motivation: libIDE clients should be simple, and they should not have to
translate token-based SourceRanges to character locations.

This also allows us to remove the dependency of DiagnosticConsumer on the
Lexer.  Now the DiagnosticEngine translates the diagnostics to CharSourceRanges
and passes character-based ranges to the DiagnosticConsumer.

13070a31bd SourceManager: make findBufferContainingLoc() always succeed.
Every valid source location corresponds to a source buffer.  There should be no
cases where we create a source location for a random string.  Thus,
findBufferContainingLoc() always succeeds.

It requires direct access to the SourceLoc internals and is generally useful
anyway.

Also centralizes the knowledge about whether the hashbang is allowed in the
SourceManager.  This fixes a bug in tokenize() because previously it just had
to guess.

                without a closing brace
