Assembler shouldn't accept invalid TLS instructions, TLS relocations
can only be used with specific instructions as specified in TLS psABI
and linker issues an error when TLS relocations are used with wrong
instructions or format. Since it is inconvenient for gcc to rely on
linker to report errors, adding TLS check in the assembler stage so
that gcc can know TLS errors earlier.
