a1e7fb4eed test: deflake chan/select3.go
On a slow or distracted machine, 0.1s is sometimes
not long enough for a non-blocking function call to complete.
This causes rare test flakes.
They can be easily reproduced by reducing the wait time to (say) 100ns.

For non-blocking functions, increase the window from 100ms to 10s.
Using different windows for block and non-blocking functions,
allows us to reduce the time for blocking functions.
The risk here is false negatives, but that risk is low;
this test is run repeatedly on many fast machines,
for which 10ms is ample time.
This reduces the time required to run the test by a factor of 10,
from ~1s to ~100ms.

Fixes #20299

1737aef270 cmd/compile: more error position tests for the typechecker
This change adds line position tests for several yyerror calls in the
typechecker that are currently not tested in any way.

Untested yyerror calls were found by replacing them with

  yerrorl(src.NoXPos, ...)

(thus destroying position information in the error), and then running
the test suite. No failures means no test coverage for the relevant
yyerror call.

For #19683

63393faedf test: speed up chan/select5
No functional changes.

Generating shorter functions improves compilation time. On my laptop, this test's running time goes from 5.5s to 1.5s; the wall clock time to run all tests goes down 1s. On Raspberry Pi, this CL cuts 50s off the wall clock time to run all tests.

Fixes #7503.

1c45f98fa3 test/chan: avoid wrap-around in memstats comparison
The select2.go test assumed that the memory allocated between
its two samplings of runtime.ReadMemStats is strictly
increasing.  To avoid failing the tests when this is not true,
a greater-than check is introduced before computing the
difference in allocated memory.

3f5edd2461 test/chan/select5.go: change "with" to "if" in templatea
I converted this program yesterday and the output is the
same as it used to be, ignoring space, but the result is
not the best expression of the algorithm.  The old {.section
Maybe} pieces are now {{with .Maybe}}, as a direct translation,
but I they should be {{if .Maybe}} as the output is just a
bool and there is no cascading.

I have verified that the output of the program is unaffected.
