We want to make the program to exit with non-zero exit code if there's an error
during dead stripping.

There are aliases for --start-group/--end-group options represented
by -( and -) respectively in the command line.

This change adds and improves the test for the alias options to be
tested.

Looks like users use this option widely than explicitly using
--start-group/--end-group.

allowRemainingUndefines() is already checked in Resolver::resolve(), so we
don't need to check it again after returning from it. It's actually not only
superfluous but buggy because a failure of resolve() does not always mean that
there is a remaining undefines.

This eliminates _elements's size check from the loop.

This patch also handles errors other than no_more_files error. They were silently
ignored.

This also reverts the LayoutPass to use std::sort as all files
have an ordinal now.

This is only a step to clean the buildbot.

-- so that command line options to specify new input files, such as
/defaultlib:foo, is handled properly. Such options were ignored before
this patch.

A file with .objtxt extension is parsed in readFile(), but because we did not
propagate that information to the calling side, calling side would try to parse
it again. This patch will fix the issue by adding an extra parameter to
readFile().

This change removes code in various places which was setting the File Ordinals.
This is because the file ordinals are assigned by the way files are resolved.

There was no other way than making the getNextFileAndOrdinal be set const and
change the _nextOrdinal to mutable.

There are so many places in code, that you would need to cleanup to make
LinkingContext non-const!

Will fix this in later commits. Not sure why the regex is not passing.

This associates resolveState to FileNodes. The control node derive
their resolution state from the inputElements that are contained in
it.

This makes --start-group/--end-group to work with ELF linking.

Output to llvm::err() is not guaranteed to be thread-safe, so it needs
to be guarded with a lock.
