On X86 windows, asflags weren't actually ever used for anything,
since assembling used x86asflags instead, and that flags list
had -DPIC already.
This fixes building shared libraries with clang for arm/aarch64
windows. (This wasn't an issue when in msvc mode before, since
we don't try to enable pic at all there, since the msvc armasm
assembler fails on our pic constructs there.)

We skipped adding it to cflags for mingw/cygwin configurations
where the compiler either complains loudly or even errors out;
do the same for target_os=win32, for the case when building with
clang in msvc mode.
This wasn't needed for the actual msvc before, since msvc uses
msvc_common_flags to filter out this flag from cflags.
When building with clang in msvc mode, no such filter is used.
This fixes building shared libraries with clang in msvc mode.

nvenc: Remove qmin and qmax constraints for nvenc vbr
[10:06:59 CEST] <BtbN> jamrial, 3303f86467 is a no-op. NV_ENC_PARAMS_RC_2_PASS_VBR is a deprecated rc mode(http://git.videolan.org/?p=ffmpeg.git;a=blob;f=compat/nvenc/nvEncodeAPI.h;h=c3a829421282d5f22f82fc285723f13eb660f053;hb=HEAD#l268).
[10:07:14 CEST] <BtbN> And the first hunk with qmin/qmax was applied to ffmpeg quite a while ago already.

In the past XvMC forced simple_idct since
it was using FF_IDCT_PERM_NONE.
However now we have SIMD variants of simple_idct that
are using FF_IDCT_PERM_TRANSPOSE and if they are selected
XvMC would get coefficients in the wrong order.
The patch creates new FF_IDCT_NONE that
is used only for this kind of hardware decoding
and that fallbacks to the old C only simple idct.
