6b00202f1b vp9/decode: add get_tile() 
factorizes the code in decode_tiles(). reading the offsets backwards
wasn't doing anything to prove tile independence

cd94eee45f Fixing clang warning. 
Warning was: "implicit conversion from enumeration type 'VPX_SCALING_MODE'
(aka 'enum vpx_scaling_mode_1d') to different enumeration type
'VPX_SCALING'".

e6dcf2aeb6 Fixing wrongly initialized tx_type variable. 
Wrong value was used in get_tx_type_4x4() function, so making
initialization before that call.

"keyframe" variable in the current code actually means that previous
frame is a keyframe because cm->frame_type has not been initialized
in read_uncompressed_header.

502912de3a changed to comply with strict aliasing rule 
The clamp operation may not affect the values of the final assigned mv
where compiler may make use of strict aliasing rule to optimize out the
clamp operation. This change made the code segments to better comply
the strict aliasing rule.

aa76cd1e49 Removing is_intra_mode() function. 
It is enough to check just block type: intra or inter. Intra block implies
intra prediction mode, and inter block implies inter mode.

8b47e1cfe1 Disable aliasing when building with Clang 
When building with new versions of Clang we encounter some issues. Work
around them by adding -fno-strict-aliasing when we detect Clang.
