[PATCH][AArch32]Allow unrestricted IT blocks

[Weiming Zhao]

Hi,

 

AArch32 allows Thumbv7 IT blocks to be executed for backward compatibility.

GCC has a  "-mno-restrict-it" flag.
http://gcc.gnu.org/ml/gcc-patches/2013-06/msg00164.html

Attached are the patches for llvm and clang that provides similar
functionality.

 

Please help to review them.

 

Thanks,

Weiming
