LOG: [X86] Emit @PLT for x86-64 and keep unadorned symbols for x86-32
This essentially reverts the x86-64 side effect of r327198.
For x86-32, @PLT (R_386_PLT32) is not suitable in -fno-pic mode so the
code forces MO_NO_FLAG (like a forced dso_local) (https://bugs.llvm.org//show_bug.cgi?id=36674#c6).
For x86-64, both `call/jmp foo` and `call/jmp foo at PLT` emit R_X86_64_PLT32
(https://sourceware.org/bugzilla/show_bug.cgi?id=22791) so there is no
difference using @PLT. Using @PLT is actually favorable because this drops
a difference with -fpie/-fpic code and makes it possible to avoid a canonical
PLT entry when taking the address of an undefined function symbol.
