No longer rely on an external tool to build the llvm component layout.
Instead, leverage the existing `add_llvm_componentlibrary` cmake function and
introduce `add_llvm_component_group` to accurately describe component behavior.
These function store extra properties in the created targets. These properties
are processed once all components are defined to resolve library dependencies
and produce the header expected by llvm-config.

Before the change attempt to link libLTO.so against shared
LLVM library failed as:
```
[ 76%] Linking CXX shared library ../../lib/libLTO.so
... /usr/bin/cmake -E cmake_link_script CMakeFiles/LTO.dir/link.txt --verbose=1
c++ -o ...libLTO.so.12git ...ibLLVM-12git.so
ld: CMakeFiles/LTO.dir/lto.cpp.o: in function `llvm::InitializeAllTargetInfos()':
include/llvm/Config/Targets.def:31: undefined reference to `LLVMInitializeVETargetInfo'
```
It happens because on linux llvm build system sets default
symbol visibility to "hidden". The fix is to set visibility
back to "default" for exported APIs with LLVM_EXTERNAL_VISIBILITY.

Change VEAsmParser to support identification with relocation information
in assmebler. Change VEAsmBackend to support relocation information in
MC layer. Change VEDisassembler and VEMCCodeEmitter to support binary
generation of branch target operands. Add REFLONG fixup and variant kind
to support new R_VE_REFLONG ELF symbol. And, add regression test in both
MC and CodeGen to check binary genaration with relocation information.

registers. Change instprinter to support MISC registers also.
Change to use auto to receive dyn_cast also.
Differential Revision: https://reviews.llvm.org/D81370
Summary:
Add regression tests of asmparser, mccodeemitter, and disassembler for
branch instructions. In order to support them, we enhance asmparser
by adding splitting mnemonic mechanism, e.g. "bgt.l.t" into "b", "gt",
and ".l.t", and parsing mechanism for AS style memory addressing.
We also implment encoding and decoding mechanism for branch instructions.

Summary:
This patch includes following items.
- Adds AsmParser and minimum AsmBackend/ELFObjectWriter/MCCodeEmitter to
support only LEA instruction in order to reduce the size of this patch.
- Adds regression test of MC layer for a LEA instruction.
- Relocations are not supported this time to reduce the size of this patch.
