  [LoongArch 1/6] Add triples loongarch{32,64} for the upcoming LoongArch target

This is the first patch to incrementally add an MC layer for LoongArch to LLVM.
This patch also adds unit testcases for these new triples.

  [LoongArch 2/6] Add ELF machine flag and relocs for upcoming LoongArch target

This patch adds necessary definitions for LoongArch ELF files, including
relocation types. Also adds initial support to ELFYaml, llvm-objdump,
and llvm-readobj in order to work with LoongArch ELFs.

  [LoongArch 3/6] Add target stub for LoongArch

This patch registers the 'loongarch32' and 'loongarch64' targets. Also adds a
simple testcase to check the output of llc --vesion containing the targets.

  [LoongArch 4/6] Add basic tablegen infra for LoongArch

This patch introduces basic tablegen infra such as
LoongArch{InstrFormats,InstrInfo,RegisterInfo,CallingConv,}.td.

For now, only add instruction definitions for LoongArch basic integer
operations.
Our initial target is a working MC layer rather than codegen,
so appropriate SelectionDAG patterns will come later.

  [Utils][LoongArch](5/6) Add a --bits-endian option to extract-section.py

This is a split patch of D115862 which adds a --bits-endian option to
extract-section to make it possible to print bits in specified endianness.
It means that we can print instruction encoding of some targets like LoongArch
as bits[0] to bits[31] from right to left by specifing --bits-endian little.

  [LoongArch][test] (6/6) Add encoding and mnemonics tests

With the benefit of D88392, instruction encoding and mnemonic testing can be
achieved within MIR files before AsmParser is ready. This patch adds such
tests which cover all basic integer instructions we defined in previous patch.
Similarly those tests will be rewrote by .s and moved to test/MC/LoongArch.
