LinkNormal mode is used by the mandatory pipeline. It only needs
to deserialize what is necessary for code generation, that is
functions with shared linkage that must be emitted into the client.
It was only used in a few tests. Those tests now use -emit-sil instead
of -emit-silgen, with some functions marked @_transparent and a few
CHECK: lines changed now that the mandatory optimizations get to run.
This changes UUID::toString() to always print using upper case. The previous
behavior was platform specific, resulting in difficulty checking UUIDs in tests.
Serialization/basic_sil.swift and SIL/Parser/basic.sil are now expected to pass
on Linux. This resolves bug SR-417.
It is just not written in a way that would let us compile it in optimized mode.
Broken SIL and assumptions that things don't get optimized away. There is little
value in making it so (we want to test serialization not optimization).

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.
