helper function which is shared by the compiler and the immediate mode
stuff. This way, diagnostic passes are run on modules imported by "-i".
Also add include guards and clean up headers a lot.

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.

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.

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.

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.

Will allow immediate execution through SIL-irgen when SIL-irgen actually exists. Also add NeedsOutput_{First,Last} symbols to the ActionType enum so that the insidious enum ordering significance there is more obvious.
