ec56677927 + Added method TObjSection.writeReloc_internal to write relocations to given section+offset without need to have a symbol at target location. 
* Optimized COFF importing code using the new method.

  - Don't create .idata$6 sections for imports by ordinal.

4d86d25c6c * -O4 switch for optimizations which are correct but which might have unexpected effects 
like field reordering (possible problems cracker classes) or using ebp as normal register (broken
      stack traces from dump_stack)
    + niln is also valid in a cse domain
    * parameters passed by reference shall have a complexity >1
    * load nodes from outer scopes shall have a complexity >1
    * better cse debugging
    + more node types added to cse
    * consider parameters passed by reference in cse
    * take care of cse in parameters in simple cases

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.

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.
