9a82fb9eb4 Fix InterlockedExchange for non-armv6+ ARMV processors. Original InterlockedExchange was not atomic in regards to the other Interlocked* functions, leading to crashes if they were used. 
Instead of directly using "swp" in InterlockedExchange, use
 - kuser_cmpxchg if available (on Linux/armel)
 - the fpc global mutex (fpc_system_lock) otherwise
to implement it.

95535ea845 - Do not create any default object sections. On targets with section-based smartlink these sections remain empty and only cause linker to do useless job of removing them. The same happens when loading object files because duplicate section names are allowed at that time. On targets without smartlink they don't stay empty, but the internal assembler creates sections when required, so not creating initial sections effectively doesn't change anything.

51af7bd440 Assembly version of fpc_ansistr_incr_ref for ARM 
Optimized to minimize load latency and icache usage. Together with the
previous fpc_ansistr_decr_ref optimization this little test programm
runs about 40% faster.

  program stringspeed;

  procedure test(s:string);
  begin
  end;

  var
    s:string;
    i: cardinal;
  begin
    s:='abcd';
    for i:=0 to $FFFFFF do
      test(s);
  end.

Even with s:='' it's about 30% faster.

b9770519f8 Assembly version of fpc_ansistr_decr_ref for ARM 
As fpc_ansistr_decr_ref is a very often called procedure in typical
pascal programs this optimized version will shave off some cycles
compared to the generic one.

It tries to avoid load latencies as much as possible and also uses the
new Z-flag functionality of the InterlockedDecrement from the previous
patch. Also FreeMem is called as a tail-function.

25e2f5f3fa Small improvement to InterlockedExchange on ARM 
Use movs instead of mov when setting the result in r0. This way the Z
flag will be set for the calling function which might allow some smaller
optimizations later on. It does not affect current code in any way,
because flags are not expected to be used across function calls.

aa21845cd9 Small optimization for OP_AND on ARM 
Especially with 64bit operators the CG sometimes generates:
and r0, r1, #0
Which just clears r0 and is equivalent with
mov r0, #0

6529307d9e Don't emit useless AND/BICs in ARM CG 
In certain cases the CG would emit something like
bic r1, r0, #0
As BIC is clearing the specified bits this is equivalent to
mov r1, r0
This patch changes the CG to emit the mov instead which the register
allocator will hopefully remove most of the time.
