[[noreturn]] can be used since Oct 2016 when the minimum compiler requirement was bumped to GCC 4.8/MSVC 2015.
Note: the definition of LLVM_ATTRIBUTE_NORETURN is kept for now.
Some behavior changes:
* `-t=d` is removed. Use `-t d` instead.
* one-dash long options like `-all` are supported. Use `--all` instead.
* `--all=0` or `--all=false` cannot be used. (Note: `--all` is silently ignored anyway)
* `--help-list` is removed. This is a `cl::` specific option.
Nobody is likely leveraging any of the above.
Advantages:
* `-t` diagnostic gets improved.
* in the absence of `HideUnrelatedOptions`, `--help` will not list unrelated options if linking against libLLVM-13git.so or linker GC is not used.
* Decrease the probability of cl::opt collision if we do decide to support multiplexing
Note: because the tool is so simple, used more for forensics instead of a building
tool, and its long options are unlikely used in one-dash form, I just drop the
one-dash form in this patch.

Many LLVM-based tools already support response files (i.e. files
containing a list of options, specified with '@'). This change simply
updates the documentation and help text for some of these tools to
include it. I haven't attempted to fix all tools, just a selection that
I am interested in.
I've taken the opportunity to add some tests for --help behaviour, where
they were missing. We could expand these tests, but I don't think that's
within scope of this patch.
This fixes https://bugs.llvm.org/show_bug.cgi?id=42233 and

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.

Summary:
The current implementation prepends a space on every line, making it difficult to compare against GNU strings.
The space appears to have come from handling --radix in rL292707. The space is for making sure there's a space between the radix and the value; however the space is still emitted even when there is no radix. This change fixes that so the space is only emitted when there is a radix.

On Windows at least, llvm-strings was crashing if it encountered bytes
that mapped to negative chars, as it was passing these into
std::isgraph and std::isblank functions, resulting in undefined
behaviour. On debug builds using MSVC, these functions verfiy that the
value passed in is representable as an unsigned char. Since the char is
promoted to an int, a value greater than 127 would turn into a negative
integer value, and fail the check. Using the llvm::isPrint function is
sufficient to solve the issue.

We have a few functions that virtually all command wants to run on
process startup/shutdown. This patch adds InitLLVM class to do that
all at once, so that we don't need to copy-n-paste boilerplate code
to each llvm command's main() function.

They don't actually change nay behaviour, as llvm-strings currently
checks the whole object without looking at individual sections anyway.
This allows using llvm-strings in a context that explicitly passes
the -a option.

Permit specifying the match length (the `-n` or `--bytes` option). The
deprecated `-[length]` form is not supported as an option. This allows the
strings tool to display only the specified length strings rather than the
hardcoded default length of >= 4.

Until we have handling for ignoring unloaded sections, simplify the logic to
the point of triviality. This fixes the scanning of archives, particularly when

This is a replacement to binutils' string tool. It prints strings found in a
binary (object file, executable, or archive library). It is rather bare and
not functionally equivalent, however, it lays the groundwork necessary for the
strings tool, enabling iterative development of features to reach feature
parity.
