Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Rui Ueyama 3f851704c1 Move new lld's code to Common subdirectory.
New lld's files are spread under lib subdirectory, and it isn't easy
to find which files are actually maintained. This patch moves maintained
files to Common subdirectory.

Rui Ueyama 2ec34544aa Move the parser for the linker script to a separate file.
LinkerScript.cpp contains both the linker script processor and the
linker script parser. I put both into a single file, but the file grown
too large, so it's time to put them into two different files.

Rui Ueyama 794366a237 Rename ScriptParser.{cpp,h} -> ScriptLexer.{cpp,h}.
These files contain a lexer, so the new names are better.
The parser is in LinkerScript.{cpp,h}.

Rui Ueyama 83043f237c Rename skip(StringRef) -> consume(StringRef).
skip() and skip(StringRef) were overloaded functions that
have different semantics. This patch rename one of the functions
to avoid function overloading.

Justin Bogner 5424e7c7dc ELF: Add a skip() overload to ignore any token
Most functions that return StringRef should check their return values,
so I'm planning on marking StringRef [[nodiscard]]. This requires
splitting up functions like next() that are sometimes just used for
side effects.

Rui Ueyama 9c1112d09a Use ScriptParserBase features to parse linker script expressions.
Previously, we have re-implemented utility functions such as `expect`
or `next` in LinkerScript.cpp. This patch reuses the existing
implementation that is in ScriptParser.cpp.

Rui Ueyama 4a46539c24 Devirtualize ScriptParserBase. NFC.
ScriptParserBase class is a container of collection of various methods
to parse linker script-ish text. It had a virtual method `run` to run
the parser. But we don't have to enforce its descendents to implement
that. It's up to them.

This patch removes pure virtual function `run`.

Adhemerval Zanella e77b5bf69f [lld] [ELF] Add ScriptParserBase class
This patch add a base script tokenizer class to decouple parsing from
linker script handling.  The idea is to use this base class on dynamic
list parsing (--dynamic-list option). No functionality added.
