65aebd22b0 + initial implementation of dwarf/eh_frame based exception handling for i386-linux, basic stuff works, open todos 
* nested exception handling statments in one procedure need to be fixed
  * clean up, finally factor out tcgprocinfo from psub at least
  * extensive testing

7aa6a2ec81 * only make a copy of the finally code in pass_1 instead of in pass_typecheck, 
to avoid an internalerror in case the finally code contains a goto outside
    the finally code (tbf/tb0209.pp)

f9668f8c03 * let de LLVM parameter manager merge multiple paralocs used to represent a 
single ordinal, as such splitting is handled by LLVM itself (and handling
    such split locations is currently not supported by our LLVM code generator)

a72a12eef6 * don't emit 0-sized parameters for LLVM: clang doesn't either, and some 
LLVM backends (like the AArch64 one) trigger internal errors when

acf02ab64b * when creating wrappers, add a prefix to parameter names to prevent them 
hiding the method name of the wrapped routine
   o also add a few more '&' prefixes to the generated wrapper code to
     prevent issues when keywords are used as identifiers

dd29088430 * simplify all type conversions for formal constants even for LLVM and JVM 
(since these happen at compile time and don't result in generated code,
     they never need extra type conversions in the code)

2330164ee2 + internal sqrt support for LLVM (faster on all platforms, necessary on 
platforms that don't have RTL support for it, as the the generic
    fpc_sqrt_real just calls runerror)

93e39fb0cd * only coerce the type of the leftover bytes of a record if the location

cec839ab30 - removed the -(m)stack-alignment parameter, as it prevents stack-realignment

df0a126064 * abstracted rest of the generic exception handling code through the 
texceptionstatehandler class + llvm overrides
  + added FPC_DummyPotentialRaise routine that gets called at the begin and end
    of try-blocks to be able to catch hardware exceptions to a limited extent
    with LLVM
