c25aba7592 * cleaned up subsetreg support (put everything in a record) 
* prepared support for elements with arbitrary bit length (as opposed
    to a multiple of 8)

90cacb4cf5 * changed result type of dwarf_reg from byte to shortint to avoid 
warning about comparison which can never be true

2adcae0cd8 * optimized register-register loading of < 64 bit values (removes superfluous code), similar to 3207 for ppc 
* fixed fixref() which did not always treat addresses as 64 bit sizes, resulting in problems using above optimization
* cleanup
* removed assembly fpc_int_real again, has problems with border cases

in an unsigned number)

8a6ebdf274 - disabled loop unrolling for level 3 optimizations since it only causes 
crashes (and even if it didn't, on its own it mainly causes code
    bloat)
