[dfsan] Turn off all dfsan test cases on non x86_64 OSs

https://reviews.llvm.org/D101666 enables sanitizer allocator.
This broke all test cases on non x86-64.

[llvm-objdump] Add -M {att,intel} & deprecate --x86-asm-syntax={att,intel}

The internal `cl::opt` option --x86-asm-syntax sets the AsmParser and AsmWriter
dialect. The option is used by llc and llvm-mc tests to set the AsmWriter dialect.

This patch adds -M {att,intel} as GNU objdump compatible aliases (PR43413).

Note: the dialect is initialized when the MCAsmInfo is constructed.
`MCInstPrinter::applyTargetSpecificCLOption` is called too late and its MCAsmInfo
reference is const, so changing the `cl::opt` in
`MCInstPrinter::applyTargetSpecificCLOption` is not an option, at least without
large amount of refactoring.

[mlir][ArmSVE] Add basic arithmetic operations

While we figure out how to best add Standard support for scalable
vectors, these instructions provide a workaround for basic arithmetic
between scalable vectors.

[RISCV] Cap legal fixed-length vectors to 256-element types

Previously, RISC-V would make legal all fixed-length vectors types whose
size are less than or equal to some function of the minimum value of
VLEN and the maximum-permissible LMUL grouping.

Due to vector legalization issues, this patch instead caps the legal
fixed-length vector types to those with 256 elements. This value was
chosen because it is the longest vector length which has corresponding
MVTs across all supported element types.
