wasmtime by default will assume the subcommand is "run" vs one of its
others, but being explicit helps clarify the actual command invoked.
For example, we pass similar looking args to wasmtime and also wasi.

We don't support these yet so let's just put them in a central location.
Once these functions are supported we can think about how to structure
the code again.
ThinLTO results in a small code size reduction, which is nice
(especially on these very small chips). It also brings us one step
closer to using ThinLTO everywhere.
LLVM wasn't aware that runtime.stackChainStart must be kept live and
can't be optimized away. With this hack, it is forced to consider
stackChainStart live at the time of the stack scan.
This fixes the corruption in https://github.com/tinygo-org/tinygo/issues/3277
This reverts commit 0b3a7280fa and updates
the documentation a little bit to explain the purpose of -gc=none. (I'm
thinking about the attiny10 by the way where defaulting to -gc=none
makes sense).
- Use compiler-rt and picolibc instead of avr-libc.
- Use ld.lld instead of avr-ld (or avr-gcc).
This makes it much easier to get started with TinyGo on AVR because
installing these extra tools (gcc-avr, avr-libc) can be a hassle.
It also opens the door for future improvements such as ThinLTO.
There is a code size increase but I think it's worth it in the long run.
The code size increase can hopefully be reduced with improvements to the
LLVM AVR backend and to compiler-rt.
Scanning of allocas was entirely broken on WebAssembly. The code
intended to do this was never run. There were also no tests.
Looking into this further, I found that it is actually not really
necessary to do that: the C stack can be scanned conservatively and in
fact this was already done for goroutine stacks (because they live on
the heap and are always referenced). It wasn't done for the system stack
however.
With these fixes, I believe code should be both faster *and* more
correct.
I found this in my work to get opaque pointers supported in LLVM 15,
because the code that was never reached now finally got run and was
actually quite buggy.
* Add test.batch flag so standalone tests print PASS on pass
* Add comment; use single-dash flag style to match usage elsewhere
* Don't add test.batch for wasmtime
* Skip test.batch unless emulator name is blank
* Remove test.batch flag; buffer test output and show only on verbose or failure
* Remove FAIL when all tests fail to match go test output
