* Added possibility to add a line of text in the property setter. (%PROPNAME%)
* Fixed TCodeOptions.Assign, missing a couple of properties.
* Fixed name of setter routine

* fillchar & fillword: check whether the count is 0 before filling anything
This fixes cases like "Writeln('')" which is used inside InternalExit if an unhandled exception happened.

This one folds
mov r1, r2, lsl #2
ldr/ldrb r0, [r0, r1]
into
ldr/ldrb r0, [r0, r2, lsl #2]
There is still some room for improvement, maybe it would be better to do this before
the register allocator runs, as we'll currently waste a register (r1 in the above example)
in many cases. That would also allow to to fold more operations, because currently if r2
gets reused between the mov and ldr we'll not be able to do the optimization.

m68k/aasmcpu.pas, taicpu.spilling_get_operation_type:
* add all Sxx instructions as "operand_write" instructions
m68k/n68kadd.pas, t68kaddnode.getresflags:
* use the correct operation in case of swapped nodes
m68k/cgcpu.pas, tcg68k.g_flags2reg:
- don't move a 0 to the register, because this will CLR it and thus the flags won't be valid anymore...
- NEG would have been the wrong operation (NOT would have been correct), but it isn't needed anyway...
* simplify the method by handling the address register case only when necessary

- removed a_jmp_cond, it's not virtual and not applicable to this CPU.
* a_loadfpu_reg_cgpara: use direct register moves for simple destinations.
* g_concatcopy: don't take address of source/destination for small amounts of data if possible, for single 32-bit moves this reduces number of generated instructions from 4 to 2.
* g_intf_wrapper: 'Self' is in R4 (a0), not R2. Fixes test/tinterface1.pp.
* mips/cpupara.pas: for functions with result returned in parameter, pass its address in a0 only if result is a record. ABI does not specify behavior for types except records/unions. At the same time, Pascal code relies on the fact that results like strings/interfaces does not change their locations, i.e. "function foo(<self>): IInterface" can be invoked as "procedure foo(<self>, out obj)". This fixes test/tdel1.pp and some Variant-related tests.

ARM status: roughly corresponds to i386 one, passes the test suite. Handles libraries, can link static libc code including basic PIC and TLS IE/LE stuff. Completely misses Thumb support. Also does not handle ABI-specific stuff, for this reason internally linked .so cannot be used for linking executables with ld. Little-endian only. Tested only on "versatilepb" QEMU virtual machine.
MIPS status: can link the compiler and at least some dynamic executables including fpmake. Some PIC support is present but almost untested. Specific header flags and sections are also not handled yet. Written to handle both endian, but tested for big-endian only ("malta" QEMU VM), including cross-linking from x86_64.

* For unresolved weak symbols, provide dynamic binding only if they are referenced via GOT or PLT (ld-compatible behavior).
* Made more TElfExeOutput properties/methods usable by descendant classes.
* x86_64/cpuelf.pas: some refactoring, handle DTPOFF relocations, prohibit TPOFF relocations in shared objects.
* i386/cpuelf.pas: set symref_from_text flags for copy relocations to work correctly.

use the correct flag for the copy loop: we jump back to the copy code as long as the value is positive aka BPL instead of BMI
This fixes around 30 tests (it fixes a quite bit more, but now some other tests seem to be broken...)

Only referencing data labels from code should change "GOT is needed" property. Writing data labels or referencing them from data should have no effect on it.
