Otherwise, the following error is observed:
src/util/cache_ops_x86_clflushopt.c:40:22:
error: arithmetic on a pointer to void is a GNU extension [-Werror,-Wgnu-pointer-arith]
40 | void *end = start + size;
| ~~~~~ ^
src/util/cache_ops_x86_clflushopt.c:44:9:
error: arithmetic on a pointer to void is a GNU extension [-Werror,-Wgnu-pointer-arith]
44 | p += cpu_caps->cacheline;
| ~ ^
This works with GNU extension enabled, but does lead to warnings
with Clang.
v2: Add to trial_c + trial_cpp checks (Erik)
v3: use c_msvc_compat_args to avoid fixing other instances of this issue (Erik)

The x86 implementation was shamelessly stolen from intel_mem.c and the
aarch64 implementaiton was based on the code in Turnip.
