Zenghui Yu b59ea3640c compiler.h: Don't use compile-time assert when __NO_INLINE__ is defined
Our robot reported the following compile-time warning while compiling
Qemu with -fno-inline cflags:

In function 'load_memop',
    inlined from 'load_helper' at /qemu/accel/tcg/cputlb.c:1578:20,
    inlined from 'full_ldub_mmu' at /qemu/accel/tcg/cputlb.c:1624:12:
/qemu/accel/tcg/cputlb.c:1502:9: error: call to 'qemu_build_not_reached' declared with attribute error: code path is reachable
         qemu_build_not_reached();
         ^~~~~~~~~~~~~~~~~~~~~~~~
    [...]

It looks like a false-positive because only (MO_UB ^ MO_BSWAP) will
hit the default case in load_memop() while need_swap (size > 1) has
already ensured that MO_UB is not involved.

So the thing is that compilers get confused by the -fno-inline and
just can't accurately evaluate memop_size(op) at compile time, and
then the qemu_build_not_reached() is wrongly triggered by (MO_UB ^
MO_BSWAP).  Let's carefully don't use the compile-time assert when
no functions will be inlined into their callers.
