Extract FLAGM (Condition flag manipulation) feature from Armv8.4-A.
Please note that FLAGM stays a Armv8.4-A feature but now can be
assigned to other architectures or CPUs.
New -march option +flagm is added to enable independently this
feature.
This patch fixes a mistake when enabling MVE instructions that disabled support
for single precision vmla and vmul for arm mode.

Originally, if the -mabi option isn't set, then assembler will set the
abi according to the architecture string in the riscv_after_parse_args.
But we should also check and reset the abi later since the architecture
string may be reset by the elf attributes. Therefore, set the abi to
the elf_flags in the riscv_after_parse_args seems too early. Besides,
we have to set the abi_xlen before assembling any instruction, so it
should be safe to call riscv_set_abi_by_arch at the place that we set
start_assemble to TRUE. However, one minor case is that we won't call
the md_assemble when we are assembling an file without any instruction.
It seems that we still need to set the abi in riscv_elf_final_processing,
to make sure that abi can be updated according to the elf arch attributes.
For the rv32i and most elf toolchains, this patch can fix the mis-matched
ABI errors for Run pr26391-5 and Run pr26391-6 testcases. Besides, it
also correct the elf header flags of the output objects. Consider the
new testcases, mabi-fail-02 and mabi-noabi-attr-[01|02|03], they are
failed before applying this patch.
But I still get the mis-matched ABI errors for the following toolchains
when runnung the riscv-gnu-toolchain regressions,
newlib-rv32imafc-ilp32f-[medlow|medany]
linux-rv32imac-ilp32-[medlow|medany]
linux-rv32imafdc-ilp32-[medlow|medany}
linux-rv64imac-lp64-[medlow|medany]
linux-rv64imafdc-lp64-[medlow|medany}
For the newlib-rv32imafc-ilp32f, although we try to choose the abi
according to the elf attributes, we will use FLOAT_ABI_SOFT rather
than the FLOAT_ABI_SINGLE for the assmebly file wihtout setting the
-mabi, but compiler will set the abi to FLOAT_ABI_SINGLE for the
C files.
As for the linux toolchains, we also get fails for Run pr26391-5 and
Run pr26391-6 testcases. Since the linux toolchain won't generate elf
attributes to correct the ISA, and the --with-arch configure option
isn't set, assembler will try to set the default arch to rv[32|64]g,
which means the FLOAT_ABI_DOUBLE will be choosed, and may be conflict
with the abi set by the toolchain.
Therefore, I would suggest that it's is more safe to set the --with-arch
when building binutils, but it may break some testcases. For example,
ld-scripts/fill and ld-scripts/empty-address-2 may be broken when c-ext
is set. We might insert R_RISCV_ALIGN to make sure the 4-byte alignment,
but the dump result will be a bit different from what the testcase expected.
However, this patch only fix the problem - the abi, elf_flags and the
instruction, which is generated according to the abi_xlen, are all fixed
once the elf attributes are set for most elf toolchains. Other mis-matched
ABI problems should be fixed when we always build the binutils with the
--with-arch= configure option.

This patch:
+ updates RAS feature system registers with new RAS 1.1 regs.
+ extends RAS/RAS 1.1 support for all architecture levels of Armv8-A.
Please note that early Armv8-A architectures do not officially support RAS
extension.
Rationale of the patch:
To ease development so that user-friendly RAS system registers operands can be
used. Certain use cases require developers to enable only more generic
architecture (e.g. -march=armv8-a) during system development. Users must use
RAS extension registers bearing in mind that system they use must support it.
The RAS (Reliability, Availability, Serviceability) extension is a
system-level extension that defines a number of system registers.
RAS 1.1 (FEAT_RASv1p1) introduces five new system registers:
ERXPFGCTL_EL1, ERXPFGCDN_EL1, ERXMISC2_EL1, ERXMISC3_EL1 and
ERXPFGF_EL1.

CSRE feature adds CSR PDEC (Decrements Call stack pointer by the size of
a Call stack record) instruction. Although this instruction has operand
(PDEC) it's instruction's only operand. PDEC forces instruction field Rt
to be set to 0b1111. This results in fixed opcode of the instruction.

This patch adds new variant (nXS) of DSB memory barrier instruction
available in Armv8.7-a. New nXS variant has different encoding in
comparison with pre Armv8.7-a DSB memory barrier variant thus new
instruction and new operand was added.
DSB memory nXS barrier variant specifies the limitation on the barrier
operation. Allowed values are:
DSB SYnXS|#28
DSB ISHnXS|#24
DSB NSHnXS|#20
DSB OSHnXS|#16
Please note that till now, for barriers, barrier operation was encoded in
4-bit unsigned immediate CRm field (in the range 0 to 15).
For DSB memory nXS barrier variant, barrier operation is a 5-bit unsigned
assembly instruction immediate, encoded in instruction in two bits CRm<3:2>:
CRm<3:2> #imm
00 16
01 20
10 24
11 28
This patch extends current AArch64 barrier instructions with above mapping.
Notable patch changes include:
+ New DSB memory barrier variant encoding for Armv8.7-a.
+ New operand BARRIER_DSB_NXS for above instruction in order to
distinguish between existing and new DSB instruction flavour.
+ New set of DSB nXS barrier options.
+ New instruction inserter and extractor map between instruction
immediate 5-bit value and 2-bit CRm field of the instruction itself (see
FLD_CRm_dsb_nxs).
+ Regeneration of aarch64-[asm|dis|opc]-2.c files.
+ Test cases to cover new instruction assembling and disassembling.

Armv8.7-a flavour please refer to Arm A64 Instruction set documentation
