This brings back the original version of D81359.
I have found several use cases now.
* Unlike GNU ld, LLD's relocation processing is one pass. If we decide to
optimize(relax) R_X86_64_{,REX_}GOTPCRELX, we will suppress GOT generation and
cannot undo the decision later. Optimizing R_X86_64_REX_GOTPCRELX can usually
make it easy to hit `relocation R_X86_64_REX_GOTPCRELX out of range` because
the distance to GOT is usually shorter. Without --no-relax, the user has to
recompile with `-Wa,-mrelax-relocations=no`.
* The option would help during my investigationg of the root cause of https://git.kernel.org/linus/09e43968db40c33a73e9ddbfd937f46d5c334924
* There is need for relaxation for AArch64 & RISC-V. Implementing this for
x86-64 improves consistency with little target-specific cost (two-line
X86_64.cpp change).
