When we originally wrote these tests we didn't have a stable and
fleshed out assembly format. Now we do so we should prefer that
over llvm ir for lld tests to avoid including more part of llvm
than necessary in order to run the test.
This change converts just 30 out of about 130 test files. More to
come when I have some more time.

Some lit tests that call llvm-ar use the 'r' flag. If the target archive
already exists and is in a corrupt state, this can cause the test to fail. We
have added 'rm -f' calls before the llvm-ar calls to increase the
robustness of the tests.

Invoking lld as ld.lld, ld.ld64, lld-link or wasm-ld is preferred
than invoking lld as lld and pass an -flavor option. We have "lld"
file mostly for historical reasons.

This is somewhat preferable since (in many cases) it allows llc
to be run directly on the .ll files without having to pass the
`-mtriple` argument.

This allows libraries to supply a list of symbols which are
allowed to be undefined at link time (i.e. result in imports).
This method replaces the existing mechanism (-allow-undefined-file)
used by the clang driver to allow undefined symbols in libc.
For more on motivation for this see:

In the long run we hope to remove this features and instead
include this information in the object format itself.

This linker backend is still a work in progress but is
enough to link simple programs including linking against
library archives.
