This patch updates the lld lit test config to use the internal shell by
default. This has some performance advantages (~10-15%) and also
produces nicer failure output. It also updates the two LLDB tests to not
require shell (so that they run under the internal shell), after first
verifying that they run and pass using the internal shell; and it fixes
one test that was not passing under the internal shell.
Port the two Process::PrintWarning functions to use the new diagnostic
events through Debugger::ReportWarning. I kept the wrapper function in
the process, but delegated the work to the Module. Consistent with the
current code, the Module ensures the warning is only printed once per
module.

This patchs adds an optional warning that is printed when stopped at a
frame that was compiled in a source language that LLDB has no plugin
for.
The motivational use-case is debugging Swift code on Linux. When the
user accidentally invokes the system LLDB that was built without the
Swift plugin, it is very much non-obvious why debugging doesnt
work. This warning makes it easy to figure out what went wrong.
