* Patch from Zeljko Avramovic to extend ordinal/float helpers

* fixed compilation for i8086 and 8-bit targets after gitlab 0049622. The conditional
ifdef checks for the ordinal helpers rewritten to be less dependendant on
defines, such as CPU16/CPU32/CPU64 and instead use sizeof(integer),
sizeof(nativeint) and sizeof(nativeuint)

* fix bootstrapping wtih 3.2.2 and -Cpcoreavx2

* adjust ToInteger of the Boolean helpers so that it returns the value of either True or False, but not any other value (e.g. in the *Bool types). This is not only Delphi compatible, but also fixes the compilation problem of the one or other 32-bit platform (like PowerPC) after e65b822a.

semantic for function results and Swap uses System.Move to not trigger
the copy mechanism.
