Clang normally disguises as GCC (defining __GNUC__), and thus get
all the normal GCC specific attributes.

Clang can also work as a drop-in replacement for MSVC, and in these
cases, it doesn't define __GNUC__, but defines _MSC_VER instead.

Even in these setups, it still supports the GCC style attributes,
thus use them, especially where there isn't any MSVC specific
version, or where the MSVC specific version doesn't work on clang
(for DECLARE_ASM_CONST).

When targeting COFF (windows), clang doesn't support this
directive (while binutils supports it for all targets).

There are samples with invalid stsc that may work fine as is and
do not need extradata change. So ignore any out of range index, and
error out only when explode is set.

This will simplify the de-MpegEncContextualization.

That code is only ever initialized with that flag set.

Fixes valgrind warning "Conditional jump or move depends on
uninitialised value(s)." from avio_flush().

Drop the packet embedded in the context.

The current code will ignore the init_get_bits() failure and do an
invalid read from the uninitialized GetBitContext.

It does not break anything currently, but should not be done anyway.

This fixes retrieving a valid profile for many of the FATE conformance samples,
allowing them to be properly decoded by the HWAccel after adding a profile check.

These bits are set by exceptions in NEON instructions.

Also print the differing bits when FPSCR is clobbered,
and use bic instead of lsl, for clearing the topmost bits.

Fixes AS error on non NEON builds introduced in 71a04721. Also
set the fpu directly to vfp in checkasm.S to cause build errors on NEON
builds.

Each const block needs to be terminated by one endconst
invocation so either call endconst after each, or just
declare plain labels to the later strings.

This fixes errors such as this, on some binutils versions:

checkasm.S:38: Error: Macro `endconst' was already defined
