An option to exchange (a lot of) compilation speed for faster code.

Unlikely. That would at best be a trade-off (possibly better support as 
long as you consider the source as C++ instead of Pascal), and something 
for which you don't need an LLVM-based code generator. That mainly 
requires patches to LLDB to add support for Pascal-specific types and 
features.
