This patch removes compiler runtime assertions that ensure the implicit
conversion are only guaranteed to work for fixed-width vectors.
With the assert it would be impossible to get _anything_ to build until
the
entire codebase has been upgraded, even when the indiscriminate uses of
the size as uint64_t would work fine for both scalable and fixed-width
types.
This issue will need to be addressed differently, with build-time errors
rather than assertion failures, but that effort falls beyond the scope
of this patch.
Returning the scalable size and avoiding the assert in getFixedSize()
is a temporary stop-gap in order to use LLVM for compiling and using
the SVE ACLE intrinsics.
