gas/
* config/tc-arm.c (arm_ext_m): Add feature bit ARM_EXT2_V8M_MAIN.
(arm_ext_v8m_main): New feature set for bit ARM_EXT2_V8M_MAIN.
(arm_ext_v8m_m_only): New feature set for instructions in ARMv8-M not
shared with a non M profile architecture.
(do_rn): New function.
(known_t32_only_insn): Check opcode against arm_ext_v8m_m_only rather
than arm_ext_v8m.
(v7m_psrs): Add ARMv8-M security extensions new special registers.
(insns): Add ARMv8-M Security Extensions instructions.
(aeabi_set_public_attributes): Use arm_ext_v8m_m_only instead of
arm_ext_v8m_m to decide the profile and the Thumb ISA.
* testsuite/gas/arm/archv8m-cmse.s: New file.
* testsuite/gas/arm/archv8m-cmse-main.s: Likewise..

include/
* opcode/arm.h (ARM_EXT2_V8M_MAIN): new feature bit.
(ARM_AEXT2_V8M_MAIN): New architecture extension feature set.
(ARM_ARCH_V8M_MAIN): Use ARM_AEXT2_V8M_MAIN instead of ARM_AEXT2_V8M
for the high core bits.

opcodes/
* arm-dis.c (coprocessor_opcodes): Add entries for VFP ARMv8-M
Mainline Security Extensions instructions.
(thumb_opcodes): Add entries for narrow ARMv8-M Security
Extensions instructions.
(thumb32_opcodes): Add entries for wide ARMv8-M Security Extensions
instructions.
(psr_name): Add new MSP_NS and PSP_NS ARMv8-M Security Extensions
special registers.
