[LLVMdev] ARM EABI Exceptions

Because both tables are "standard" ?

Here is how EH was implemented first for x86:
1. LLVM was made to emit tables for some "easy" examples, this
involves some low-level stuff like register moves, encoding, etc. At
this point one can use LLVM-generated .s files with gcc-provided
unwinding library.
2. Necessary EH intrinsics was implemented
3. More refinements (PIC mode, etc.)
