The issue is uncovered by #47698: for assembly files, -triple= specifies the
full target triple while -arch= merely sets the architecture part of the default
target triple, leaving a target triple which may not make sense, e.g.
riscv64-apple-darwin.
Therefore, -arch= is error-prone and not recommended for tests. The issue has
been benign as we recognize $unknown-apple-darwin as ELF instead of rejecting it
outrightly.
Due to the nature of the issue, we don't see the issue in tests using
architectures that any of Mach-O/COFF/XCOFF supports.
Summary of changes:
- Changed parser to eliminate generation of excessive error messages;
- Corrected lit tests to match all expected error messages;
- Corrected lit tests to guard against unwanted extra messages (added option "--implicit-check-not=error:");
- Added missing checks and fixed some typos in tests.

It's not clear to me if this is always better than
doing ds_write2_b64 This adds the constraint of
a 128-bit register input instead of a pair of
64-bit.
