fa3b0ca312 * support marking defs created via the getreusable*() class methods as 
"don't free even if not registered"; use for defs that may not be written
    to a ppu file, but that must nevertheless survive the compilation of the
    current module
  * mark all defs created for para locations as "don't free even if not
    registered", because we don't discard and recalculate all para locations
    after a module has been compiled (since that's not needed)
   o solves issues if the paralocations for a routine in the interface of
     unit A are calculated while the implementation of unit B gets
     compiled, and a new reusable type is allocated at that point which
     is not used anywhere else (after r32160)

991e1f49bd * store a pointer to the used tasminfo record in every assembler writer, so 
that we can use assembler writers with different conventions from the
    currently set target_asm (e.g. an x86 assembler writer for inline assembly
    in LLVM IR)

b3d0197f98 * factored out the output file handling (mostly writing data) from the 
external assembler writer, so we can reuse the archtecture-specific
    writers to write inline assembly in LLVM IR files

0fc1fd6ac1 * replaced current_procinfo.currtrue/falselabel with storing the true/false 
labels of LOC_JUMP in the node's location. This generates some extra jumps
    for short circuit boolean and/or-expressions if optimizations are off, but
    with optimisations enabled the generated code is the same (except for JVM
    because the jump threading optimisation isn't enabled there yet).

f85a8159ef * compiler/mips/cpuinfo.pas: removed "FPU_" prefixes from FPU names, not necessary because compiler inserts one itself. 
* rtl/embedded/system.pp: removed (commented out) FPU initialization from initialization of system unit, was dead code anyway because FPC_HAS_FEATURE_FPU is never defined and "feature FPU" does not exist.
* rtl/mips/*.inc: don't compile FPU instructions if compiling RTL with -CfNONE or -CfSOFT (however, handling these switches for MIPS targets in compiler needs further fixing).
