vc1dec: Update destination pointers in context for fields
...
This replaces a large number of checks for the second field by
fixing the pointers when they are setup.
This should also fix I/BI field pictures.
Changes checksums for vc1_sa10143, the file becomes slightly closer
to what the reference decoder outputs.

configure: Explicitly disable PIC when targeting win32/mingw
...
These platforms do not have any notion of PIC. On some compilers,
enabling pic produces a number of warnings.
This avoids trying to produce PIC loads in the ARM assembly - there
are no relocation types in PE/COFF that correspond to
BFD_RELOC_32_PCREL (R_ARM_REL32 in ELF).
As a side-effect, this avoids enabling PIC on mingw64, getting rid
of the warnings about PIC not having any effect on that platform.
