implement `make_integer_sequence` in terms of intrinsics whenever possible #2384

ericniebler · 2024-09-06T16:40:21Z

Description

MSVC has the __make_integer_seq intrinsic, but our implementation of make_integer_sequence isn't using it. this PR corrects that.

additionally, it uses the __integer_pack intrinsic on gcc.

fixes #2367

this PR defines _LIBCUDACXX_HAS_MAKE_INTEGER_SEQ when _CCCL_MSVC_VERSION_FULL >= 190023918 is true.

it also conditionally implements make_integer_sequence in terms of __integer_pack if such a builtin is available.
