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 FlagParser is populating a static global class with the
unrecognized flags when parsing. That global class has a
dcheck that limit the number of unrecognized flag to 20.
```
class UnknownFlags {
static const int kMaxUnknownFlags = 20;
const char *unknown_flags_[kMaxUnknownFlags];
int n_unknown_flags_;
[...]
void Report() {
if (!n_unknown_flags_) return;
Printf("WARNING: found %d unrecognized flag(s):\n", n_unknown_flags_);
for (int i = 0; i < n_unknown_flags_; ++i)
Printf(" %s\n", unknown_flags_[i]);
n_unknown_flags_ = 0;
}
};
UnknownFlags unknown_flags;
```
Unittests based on that class must reset the counter 'n_unknown_flags_' or
the next usage of that class may fail arbitrary. This can be done by
reporting the pending unknown flags.

The new parser is a lot stricter about syntax, reports unrecognized
flags, and will make it easier to implemented some of the planned features.
llvm-svn: 226169
Add CommonFlags::SetDefaults() and CommonFlags::ParseFromString(),
so that this object can be easily tested. Enforce
that ParseCommonFlagsFromString() and SetCommonFlagsDefaults()
work only with singleton CommonFlags, shared across all sanitizer
runtimes.
llvm-svn: 224617
Extend ParseFlag to accept the |description| parameter, add dummy values for all existing flags.
As the flags are parsed their descriptions are stored in a global linked list.
The tool can later call __sanitizer::PrintFlagDescriptions() to dump all the flag names and their descriptions.
Add the 'help' flag and make ASan, TSan and MSan print the flags if 'help' is set to 1.
