Rainer Orth c2b9e9674d [fir] Fix FlangOptimizerTests link on Solaris
As reported in Issue #53690,
`tools/flang/unittests/Optimizer/FlangOptimizerTests` `FAIL`s to link on
Solaris:

  Undefined                       first referenced
   symbol                             in file
  _ZN3fir7runtimeL8getModelIcEEPFN4mlir4TypeEPNS2_11MLIRContextEEv lib/libFIRBuilder.a(Reduction.cpp.o)

which is `mlir::Type (*fir::runtime::getModel<char>())(mlir::MLIRContext*)`.

`clang++` warn's

                              ^

Fixed by adding an explicit template instantiation for `getModel<char>`.  I
suppose this is necessary because on Solaris `char` is `signed`.

Tested on `sparcv9-sun-solaris2.11`.
