8dc6ebb5ed rtl/generic.inc, minor optimizations: 
* fpc_help_constructor: call platform-optimized version of FillChar directly instead of going through generic overloaded version.
* don't compile software multiplication routines if not necessary (the interface part already has similar $ifdef around)
* fpc_shortstr_append_shortstr: use sizeint instead of integer (the latter is 16-bit, produces less efficient code on most platforms)

c5dfa9d354 * fixed fpc_shortstr_concat() in case the max length for the destination is 
already smaller than the length of the first string (probably cannot
    happen currently, but may be in the future as a result of optimizations)

efea42bcdf * rewrote Ror/Rol/Sar so that it can be completely folded into a const by the compiler 
if possible, the copied (dist and xxx) expressions are folded by the CSE so they don't hurt

b912e00440 * renamed rol/ror functions into rolbyte/rolword/roldword/rolqword 
(and the same for ror), because their operation is very dependent on the
    operand size, and it's fairly easy to misjudge the bitwidth of the outcome
    of an expression in Pascal if you are not intimately familiar with the
    language (or if you don't know the exact types of all involved values in
    an expression)

22aacd2a60 * return 0 for length(pchar(0)), like Kylix does (using corrected and 
multi-platform version of patch in r12461, which caused the i386 version
    of fpc_pchar_length to return 0 in all cases, which used tabs, and did
    not include a test case)

bc9e7c5580 * fixed syntax errors in r11708 (and it wasn't tested in the nightly 
Sparc regressions tests because Solaris is an FPC_USE_LIBC platform,
    and these use memset rather than the generic fillchar)

95637dea75 * fixed swapendian(smallint) (bug found by Joost van der Sluis) 
* based swap(smallint) and swap(word) on swapendian(smallint/word),
    since the same bug was already fixed in swap(smallint) in r6752
    (so these routines now share the same code)
  * fixed potential range error in swapendian(word)
  + added basic test for the above four routines

9cec910eb9 * changed *string_to_*chararray helpers from functions into procedures 
because on win64 the location of a function result can depend on its
    size (so some chararrays had to be returned in registers and others
    by reference, which means it's impossible to have a generic function
    declaration which works in all cases) (mantis #8533)
  * pad constant string assignments to chararrays with #0 up to the
    length of the chararray for 2.0.x compatibility (fixes
    tests/test/tarray3)

a2c3826281 * changed fpc_big_chararray and fpc_big_widechararray from 
array[0..1023] into array[0..0], because they're used as
    dummy return types for the Xstring_to_chararray helpers,
    and if a smaller array is actually passed as result then
    having a larger array declared will cause -gt to
    overwrite other data
