Instead of reusing a fixed-size buffer, which causes problems when error messages refer back to previous inputs and corrupts AST references in *LiteralExpr that point back into source buffers, allocate each REPL input into its own buffer with its own SourceMgr entry. Fixes <rdar://problem/13387167>, crashes when using :dump_ast on expressions containing integer/float literal expr nodes, and hopefully sporadic buildbot failures running the Interpreter/repl test.

Dump the module IR just prior to instantiating the execution engine, and log the start of module initializers, static constructors, and main().

This matches the behavior for compilation, and lets us test modules that
don't need any extra codegen.
With this, typealiases of builtins can be used end-to-end in modules!

by TranslationUnit. This list existed solely to allow name lookup of
an unbound IdentifierType to know its DeclContext. Instead of indirecting
through this list, just store the DeclContext in the IdentifierType in its
uninitialized state.
This eliminates a really terrible performance fixme about scanning the list,
eliminates the management fiddling around with this list in the parser, and
is generally much cleaner.

Remove '@' from the operator character set, but add the math, symbol, punctuation, arrow, and line- and box-drawing characters. Also allow operators to contain (but not start with) combining characters--this should be safe, because identifiers can't start with combining characters either, and we don't allow them anywhere else.

Original message:
SIL Parsing: add plumbing to know when we're parsing a .sil file
Enhance the lexer to lex "sil" as a keyword in sil mode.

redefinition (or linkage type) bug that causes two tests to fail. I filed
rdar://13670581 to track this and am plowing forward, since they seem minor.

The repl is sometimes failing to write anything to stdout when it is
being redirected to a file (as in test/Interpreter/repl.swift). it
looks like an editline bug on 10.8. explicitly fflushing stdout
seems to help.

logic in Sema (previously, some of it was in tools/Swift/Frontend.cpp) and eliminates
redundancy between expr and pattern printing. This also eliminates most of the invalid
ASTs that the repl was producing (there is still one left).
This commit reenables the disabled REPL testcase from my last big change.

'-i' code was always getting emitted at -O2 regardless of the -O flag, which enables the "standard library hack" that pulls in IR for all of swift.swift. For -i optimization is often less important than responsiveness, so allow the optimization level to be specified by a flag and default to -O0 normally.

If you're pasting blocks of prewritten code into the REPL, you don't want it to double-indent. Saying ':autoindent off' before you paste now disables the automatic indentation so you can paste preformatted code.
Swift SVN r4222
Rerender inputs in bold after they've been entered. Colorize non-REPL output, cyan for normal responses, and green for REPL directive responses. (In my terminal setup these were the least retina-searing members of the vast and nuanced ANSI color palette.)
Swift SVN r4217
Package up some useful REPL context into a header-able REPLContext class. Move the response metavar index there instead of having it as a gross mutable static variable.
Swift SVN r4203
If a REPL input parses to an expression, bind it to the next available variable 'r<n>', and print the result as if it were a name binding. Don't bind a variable if the expression consists of a lone DeclRef, and don't print the binding if it has void type.
Swift SVN r4201
Document how we're relying on the synchronous-ness of CFMessagePortSendRequest to serialize AST access between the REPLInput and REPLEnvironment threads, and remove an inaccurate comment about EL_GETCFN.
Swift SVN r4178
The REPL was accreting global_ctors and rerunning all global initializers ever registered before every entry. Change it so that it only runs global initializers once and so that the ObjC initialization stuff that needs to happen on a per-entry basis just gets dropped directly into the main() for each entry.
Swift SVN r4154
In the repl, if a replExit function is defined, call it when the repl is exiting. In the stdlib, add an atREPLExit function that pushes replExit handlers onto a vector and a replExit function that invokes those handlers. In swiftAppKit, have REPLApplicationMain use atREPLExit to terminate the application when the REPL is exited.
Swift SVN r4132
This runs the REPL with the editline interactor in a separate thread while the main thread runs a CFRunLoop. The interactor thread then sends REPL inputs through a CFMessagePort which the main thread run loop responds to.
Swift SVN r4128
Break out the code that actually puts together an editline input from the code that parses, compiles, and executes the code, with an eye toward letting the former run in a thread while the latter becomes a CFRunLoop client.
Swift SVN r4124
If the completion prefix has a '.' behind it, guesstimate a context expression by lexing backward through an identifier(.identifier)* dotted path, then attempt to parse and typecheck that expression to decide on a base type in which to find completions.
