When enabling the early swift driver on Windows, these tests need to be
adjusted for the new driver name that is reported. Add an additional
spelling for the driver to accommodate that for the testsuite.
Build swift-frontend as the primary Swift binary, and have
swift/swiftc/etc. symlink over to it. This is a step toward allowing
swift-driver to replace the swift and swiftc binaries.
Clang 8 or 9 seems to have changed from EXE to exe. Allow both
capitalizations (which is not important in Windows) as a workaround.
Maybe in the future we can remove the uppercase option.
Add a new action, LoadModuleJobAction, that the driver can use to schedule a
load of a given module before we fan out and invoke the frontend multiple
times. This gives the module interface loader a chance to compile it from a
module interface before we start with parallel invocations, avoiding starting
potentially dozens of redundant compiles of a large module. Start by using this
on the standard library.

The "Tool" abstraction wasn't buying us enough to deserve the added
complexity. Now a ToolChain turns Actions into Jobs, and every helper
tool is searched for relative to Swift first. Much simpler.

Most of the tests just got moved to swiftc, but some of them were
duplicated to apply to both swiftc and swift. A handful still use the
existing 'swift' because they are for the existing '-i' syntax.
Note: this means config.swift_driver now uses the staging symlink
'swifti'. The only thing preventing us from dropping the 'i' and getting
rid of the old interface is that Xcode hasn't moved to swiftc yet

First, use -driver-print-output-file-map to ensure that the map we write out is, in fact, being deserialized properly.
Then, use -driver-print-bindings to ensure that we are preferring values in the output file map to default output paths.
