[GlobPattern] Support brace expansions
Extend `GlobPattern` to support brace expansions, e.g., `foo.{c,cpp}` as discussed in https://reviews.llvm.org/D152762#4425203.
The high level change was to turn `Tokens` into a list that gets larger when we see a new brace expansion term. Then in `GlobPattern::match()` we must check against each token group.
This is a breaking change since `{` will no longer match a literal without escaping. However, `\{` will match the literal `{` before and after this change. Also, from a brief survey of LLVM, it seems that `GlobPattern` is mostly used for symbol and path matching, which likely won't need `{` in their patterns.
See https://github.com/devongovett/glob-match#syntax for a nice glob reference.

[Support] Rewrite GlobPattern
The current implementation has two primary issues:
* Matching `a*a*a*b` against `aaaaaa` has exponential complexity.
* BitVector harms data cache and is inefficient for literal matching.
and a minor issue that `\` at the end may cause an out of bounds access
in `StringRef::operator[]`.
Switch to an O(|S|*|P|) greedy algorithm instead: factor the pattern
into segments split by '*'. The segment is matched sequentianlly by
finding the first occurrence past the end of the previous match. This
algorithm is used by lots of fnmatch implementations, including musl and
NetBSD's.
In addition, `optional<StringRef> Exact, Suffix, Prefix` wastes space.
Instead, match the non-metacharacter prefix against the haystack, then
match the pattern with the rest.
In practice `*suffix` style patterns are less common and our new
algorithm is fast enough, so don't bother storing the non-metacharacter
suffix.
Note: brace expansions (D153587) can leverage the `matchOne` function.

Reapply r375051: [support] GlobPattern: add support for `\` and `[!...]`, and allow `]` in more places

Reapply r375051: [support] GlobPattern: add support for `\` and `[!...]`, and allow `]` in more places
Reland r375051 (reverted in r375052) after fixing lld tests on Windows in r375126 and r375131.
Original description: Update GlobPattern in libSupport to handle a few more cases. It does not fully match the `fnmatch` used by GNU objcopy since named character classes (e.g. `[[:digit:]]`) are not supported, but this should support most existing use cases (mostly just `*` is what's used anyway).
This will be used to implement the `--wildcard` flag in llvm-objcopy to be more compatible with GNU objcopy.
This is split off of D66613 to land the libSupport changes separately. The llvm-objcopy part will land soon.

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.

That happens because ® has int value -82. And chars are used as
array index in code, and are signed by default.
