Crap. 8.3 eats this just fine. And I guess we can accomodate old gccs
by having BIT() evaluate the enclosing UL() macro into its __ASSEMBLY__
variant but it ain't worth the trouble.

It stringifies just fine with the BIT() macro too:
# 187 "arch/x86/kernel/cpu/sgx/encls.h" 1
1: .byte 0x0f, 0x01, 0xcf;

ENCLS is a ring 0 instruction that contains a set of leaf functions for
managing enclaves [1]. Enclaves SGX hosted measured and signed software
entities, which are protected by asserting the outside memory accesses and
memory encryption.
