617cc6984b * call DoUnhandledException instead of RunError(217) when the the psabi eh 
unwinder returns an error (this is usually because there is no outer
    exception catching frame anymore -> unhandled exception) (based on patch by
    Cyrax, mantis #35751)

42f82f4d40 * the libunwind API resides in libgcc_s on Linux 
o also link against libc (the current llvm code generator assumes it for
     memcpy, and libgcc_s depends on it anyway)

aff3a15081 * call runerror(217) instead of halt(217) when using Dwarf-EH in similar 
cases as where this happens with the standard SjLj-base exception handling

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

4bc0e49878 - removed unused FPC_psabieh_can_catch() 
* added missing exit in FPC_psabieh_find_action_record
  * fixed type error in call to _Unwind_SetGR() (caught by compiler fix for
    that intrinsic)

b2d1ab7f05 * basic helpers for DWARF/PSABI EH-based exception handling (based on 
GCC 4.2.1's libstdc++/libsupc++)
   - compile RTL with -dFPC_USE_PSEABIEH to include
   - the x86-64 compiler currently crashes if it has been compiled with
     optimizations (the eh_return_data_regno function from cpubase
     probably triggers mantis #34385)
