* Migrate most of our tests to use `split-file` instead of `echo`
* Remove individual `rm -f %t/libfoo.a` commands in favor of a top-level `rm -rf %t`
* Remove unused `Inputs/libfunction.s`

Summary:
As mentioned in https://reviews.llvm.org/D81326#2093931, I'm not sure it
makes sense to use the default target triple to determine -arch.
Long-term we should probably detect it from the input object files, but
in the meantime it would be nice not to have to add it to all our tests
by using a convenient default.

Summary: After {D81326} landed, some tests started failing if they did
not have `-arch` specified. I think one of the reasons happened was due
to the fact that we were taking a reference to a temporary value that
was freed too early. Fixing that got the error to go away on my local
Linux machine.

Use the default target triple configured by the user to determine the
default architecture for `ld64.lld`. Stash the architecture in the
configuration as when linking against TBDs, we will need to filter out
the symbols based upon the architecture. Treat the Haswell slice as it
is equivalent to `x86_64` but with the extra Haswell extensions (e.g.
AVX2, FMA3, BMI1, etc). This will make it easier to add new
architectures in the future.
This change also changes the failure mode where an invalid `-arch`
parameter will result in the linker exiting without further processing.
With this change, basic archive files can be linked together. Input
section discovery has been refactored into a function since archive
files lazily resolve their symbols / the object files containing those
symbols.
