ff2fff365f + added x86 compiler intrinsics fpc_x86_sti and fpc_x86_cli, which generate the 
'sti' and 'cli' instructions

6cd88a24dc * release al/ax/eax immediately after the 'in', before (instead of after) moving 
it to the destination imaginary register. This generates better code.

fdc896ad0a + inline support for the x86 'in' and 'out' instructions. Currently only enabled 
in the i8086-msdos 'ports' unit, but will be enabled on other targets (e.g.
  go32v2) in the future as well. 32-bit 'in' and 'out' not inlined on i8086, but
  will be on i386 and x86_64.

4686f61002 * keep track of the temp position separately from the offset in references, 
so that they can still be freed after the reference has been changed
    (e.g. in case of array indexing or record field accesses) (mantis #33628)

efc5e339d0 * use an enum instead of integer constants to represent inline numbers 
* compinnr.inc include file converted to a unit
* inline number field size stored in ppu increased from byte to longint
* inlines in the parse tree (when written with the -vp option) now printed with
  their enum name, instead of number

a25ebbba3e + added volatility information to all memory references 
o separate information for reading and writing, because e.g. in a
     try-block, only the writes to local variables and parameters are
     volatile (they have to be committed immediately in case the next
     instruction causes an exception)
   o for now, only references to absolute memory addresses are marked
     as volatile
   o the volatily information is (should be) properly maintained throughout
     all code generators for all archictures with this patch
   o no optimizers or other compiler infrastructure uses the volatility
     information yet
   o this functionality is not (yet) exposed at the language level, it
     is only for internal code generator use right now
