3385ce92a2 * Always generate CFI-information. During linking it can be omitted when 
no debug-information is requested. On Linux this needed a change in the
   linker-script. On Windows it already works as desired. Other targets
   may need some adjustments as well.

ca399f3c71 * don't generate high-level CFI statements when the selected assembler 
does not support them, even if the target normally uses them
   o fixes assembling with -Aas-darwin for i386/arm/x86-64 (on OS
     versions that used those)

0fbd418cb7 * generate CFI data only if we're either using it for exception handling or if debug output is enabled (or should this only be generated for targets that in theory support DWARF exception handling?). This removes unnecessary bloat from e.g. Windows binaries
