Foundation needs to be loaded early in the process for Swift's runtime
to properly initialize bridging support; otherwise it may cause issues
like unrecognized selectors. When scripting, load Foundation early in
performFrontend before any swift code runs.

The REPL was using the CompilerInstance to stash this parameter, then it would immediately move it into IRGen. Drop the setter and pass this data directly.
No intended functionality change, although this may make it easier to
get the REPL up and running on Linux. This is still useful for compiler
hackers even if it's not an end-user feature.

This works, except when you launch it in -parse-stdlib mode, where running that expression fails, because Swift.Void wasn't pulled in, and that failure causes the REPL to quit
This patch passes down the -parse-stdlib flag to the REPL initialization code, such that it does not try to run any warm up code in -parse-stdlib mode

I am going to use this in a forthcoming patch which creates a special mode
called "ParanoidVerification" which runs the verifier after all passes.
"ParanoidVerification" will be by default off and will be used on the swift-fast
buildbot to help catch bugs which might be hidden by optimizations being run.

In order to implement immediate and REPL modes in swift_driver, this functionality
needs to be in a library (instead of directly in the swift executable).
