Add support to linker for the following Z features used in LLVM:
 - Bit manipulation: Zbe, Zbf, Zbm, Zbp, Zbr, Zbs and Zbt.
 - Half-precision floating-point: Zfh.
 - Vector segment load/store: Zvlsseg.
 - Vector AMO operations: Zvamo.

bfd/ChangeLog:

	* elfxx-riscv.c (riscv_std_z_ext_strtab): Add zbe, zbf, zbm, zbp,
	zbr, zbs, zbt, zfh, zvamo and zvlsseg.
