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.

aacef757ed Move decompose from PrettyStackTrace.cpp to the SourceManager 
It requires direct access to the SourceLoc internals and is generally useful
anyway.

2c7dc9e967 SourceManager::setCodeCompletionPoint(): allow setting code completion point multiple times. 
This is required to do multiple completions in the REPL.

7684d6dc2a Add a good diagnostic for a hashbang line when it is not allowed 
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.

5cea4ebf41 Code completion: put CodeCompletionOffset on SourceManager instead of passing 
around everywhere

Fixes:
rdar://14585108 Code completion does not work at the beginning of the file
rdar://14592634 Code completion returns zero results at EOF in a function
                without a closing brace
