7ea5dbcb83 cavsdec: Fix assertion failure. 
The assert in decode_mb_b() is replaced by a normal error check for the
case that can occur with a damaged or crafted bitstream.

5fa22ae346 configure: Adjust the xgetbv instrinsic check 
The 64 bit cl.exe version 16.00.30319.01 crashes with an internal
compiler error on the current check (and thus deduces it isn't
supported, even if the actual usage in libavuil/x86/cpu.c works
fine), but by assigning the value from the intrinsic to a variable,
or returning it, it works fine.

This error is fixed in cl.exe version 16.00.40219.01.

88a3569917 configure: Don't try to enable the log2 function on msvcrt 
Some msvcrt versions (the static 64 bit libc in MSVC 10) have
a log2 function, but there is no declaration for it in the headers.
Therefore, the normal configure check might find it, but it can fail
during build or at runtime, depending on whether implicit function
declarations are an error or not.

Therefore simply ignore this function on this platform.
