MIPS/LD: Reject tprel_hi and tprel_lo relocations in shared library

bfd/
	* elfxx-mips.c (_bfd_mips_elf_check_relocs): Generate error
	for TLS_TPREL_HI16(/LO16) relocations in shared library.

ld/
	* testsuite/ld-mips-elf/pic-reloc-5.s: Add tests for
	%tprel_hi and %tprel_lo relocations.
	* testsuite/ld-mips-elf/pic-reloc-6.s: Likewise.
	* testsuite/ld-mips-elf/pic-reloc-5.d: Update accordingly.
	* testsuite/ld-mips-elf/pic-reloc-6.d: Likewise.
	* testsuite/ld-mips-elf/pic-reloc-tls.ld: New test linker
	script file.
