default value (mantis #22343)
* give an error when specifying an invalid default value (e.g. a
floating point number for a longint parameter)

since they require function calls and it's not possible to call functions
inside constant blocks (and because current_procinfo is not necessarily
valid when a constant block is parsed, this moreover crashes the compiler)

Currently the register spiller can not handle the "bond" between IT* and
a following instruction, sometimes breaking them apart, which breaks the
build or worse the result.
So for now we're not emitting A_IT* in second_cmp64bit anymore but use a
conditional jump instead.
This fixes Mantis #22520

We're currently using rev for armv6+, but FPC 2.6 could not handle the
instruction. So if somebody wants to build trunk it can't be for armv6+.
We'll circumvent the problem by always using the the generic code when
build with FPC 2.6.

In r21686 I've introduced optimized 64bit shifts for ARM. But the
methods did not check for which machine it has to generate the code.
This patch disables the optimized code for now if the target is in
cpu_thumb2 and falls back to the generic code.
There are 2 problems with the current code:
1.) Thumb-2 does not support shift by register on all data instruction
as ARM does.
2.) The code does not generate the required IT-block for the conditional
executed code.

The old code generated a strange IT-sequence:
IT EQ
MOVEQ r0, #1
IT NE
MOVNE r0, #1
Now we generate:
ITE EQ
MOVEQ r0, #1
MOVNE r0, #1
IT stands for IfThen, ITE for IfThenElse it has a couple of other forms
where the instruction gets extended to handle more of the following
instructions. So we have ITEE, ITETE etc, up to 4 instructions can be
handled.

This adds some small improvements to Move_pld and Move_blended.
1.) Overlapping memory is handled as "unusual" and the code is placed at
the end of the function for better icache/bpu performance
2.) Fused the overlap check into 3 instructions with a single jump
instead of 5 instructions with 2 jumps.
2.) Use ldmia/stmia with 2 registers instead of ldr/str for faster
copying.
3.) Some code cleanup
git-svn-id: trunk@21992 -
+ Dedicated constructor TElfObjSection.create_reloc for relocation sections.
+ pass symbol name offset separately to TElfSymtab.writeSymbol, this is necessary for two-pass writing of dynamic symbol tables.

* check "A op B" and "B op A" again for operators that can be commutative (all binary ones except shl, shr, div, mod, **, / and -)
* also check for Nil for classrefdefs if left side is a pointer (allows "TClass var" <>/= Nil again, after the above changes)
* don't allow overloads for "implicit pointer type <>/= pointer" and the other way around (this fixes non compiling Objective Pascal test tobjc21.pp and also the new toperator87.pp test)
* some formating corrections
+ added test for "TObject <> Pointer"
+ added test for "TClass <>/= Nil"

The changes are built up in a way that all operators on two given types are not allowed if a default implementation for that operator exists. This implies that there is a possibility to have a overload work for (in this order) type A and B, but not for B and A. This is for example the case for Set + Enum (which seems to have a default implementation) where Enum + Set is allowed. The added tests try to detect as many default implementations as feasible, but can't cover everything...

hierarchies from other units that were compiled without debug information
in case not all classes from the hierarchy are explicitly used

+ Two stubs (TExeOutput.Load_DynamicObject and TObjInput.CanReadObjData) to override in ELF linker.
+ Stop linking if errors were detected while loading object files.
* Changed TStaticLibrary to TObject. It is never looked up by name, so hashing is redundant; moreover its name has been changed to TCmdStr, which may be trimmed by TFPHashList.
