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).
