2ae3ce79bb * ARM: Never use the "BLX label" instruction. Use "BL label" instead. 
The linker will always change BL to BLX if necessary, but not vice versa (linker version dependent).
  "BLX label" ALWAYS changes the instruction set. It changes a processor in ARM state to Thumb state,
  or a processor in Thumb state to ARM state.

71cdedea82 Add missing NOP, and B instruction forms. 
Move ThumbFunc flag from section to symbol.
Make .w forms optional the other way around. If .w is explicitly put on an instruction the assembler should always chose a wide form.

9e5979e8be Implemented UAL syntax support in the ARM assembler reader. Can be toggled with a field for now, but not implemented yet. Still using pre-UAL syntax for now. 
Switched codegeneration of VFPv2 and VFPv3 to use UAL mnemonics and syntax.
Updated VFP code in RTL to use UAL syntax too.
Added preliminary ELF support for ARM.
Added support for linking of WinCE COFF files. Should work for with a standard ARMv4-I target.
