13e2572140 Remove unnecessary compiler version checks in rtl/arm/arm.inc 
The CPUARM_HAS_* flags are never defined in 2.6, so there is no reason
to check for the compiler version.

c29e6bbcb8 * disabled assembler implementations of fpc_ansistr_decr_ref/ 
fpc_ansistr_incr_ref for Darwin/ARM: they don't follow the Darwin/ARM
    ABI for function calls, the code already contains enough ifdefs and
    I don't want to spend time on maintaining OS-specific assembler
    implementations

6729164fcc Work around load latency in InterlockedExchange for ARM 
An LDR will have two load latency cycles on most ARM implementations,
moving the
  mov r4, r0
two instructions away from the corresponding ldr will avoid the stalls.

f252fd369e Tried to reorganize the ARM define mess in rtl/arm/arm.inc. Instead of requiring to enumerate all possible ARM variants each time a CPU feature is used, add a define of the format CPUARM_HAS_XXX and use that. Note that a better solution would be to properly implement the compiler cpuinfo infrastructure, however that is much more work. 
+ CPUARM_HAS_BX is defined if the CPU supports the BX* instruction
  + CPUARM_HAS_REV is defined if the CPU supports the REV instruction. Note that you still have to check for compiler versions > 2.6.0 since the assembler reader of 2.6.0 does not understand that instruction.
  + CPUARM_HAS_IDIV is defined if the CPU supports the sdiv, udiv instructions. Use of this fixes a bug where previously these instruction were only used for armv7-m, while cortex3m cpus also support it.
  + CPUARM_HAS_LDREX is defined if the CPU supports the ldrex/strex instructions. Use of this fixes a bug with armv7(-a) cpus where this path has not been used.
  + SYSTEM_HAS_KUSER_CMPXCHG is defined if the system (mainly OS) support the kuser_cmpxchg functions. Use of this fixes a bug where ARMHF systems did not use it for synchronization (although ARMHF is armv7+ only, i.e. the LDREX path is used anyway)
