Feng Zou 636beb6a28 [X86][LLD] Handle R_X86_64_CODE_6_GOTTPOFF relocation type (#117675 )

For

    add %reg1, name@GOTTPOFF(%rip), %reg2
    add name@GOTTPOFF(%rip), %reg1, %reg2
    {nf} add %reg1, name@GOTTPOFF(%rip), %reg2
    {nf} add name@GOTTPOFF(%rip), %reg1, %reg2
    {nf} add name@GOTTPOFF(%rip), %reg

add

    R_X86_64_CODE_6_GOTTPOFF = 50

in #117277.

Linker can treat R_X86_64_CODE_6_GOTTPOFF as R_X86_64_GOTTPOFF or
convert the instructions above to

    add $name@tpoff, %reg1, %reg2
    add $name@tpoff, %reg1, %reg2
    {nf} add $name@tpoff, %reg1, %reg2
    {nf} add $name@tpoff, %reg1, %reg2
    {nf} add $name@tpoff, %reg

if the first byte of the instruction at the relocation offset - 6 is
0x62 (namely, encoded w/EVEX prefix) when possible.
