Typechecking treats all untyped numbers as integers for the purposes
of validating operators. However, when I refactoring constant
operation evalution in golang.org/cl/139901, I mistakenly interpreted
that the only invalid case that needed to be preserved was % (modulo)
on floating-point values.
This CL restores the other remaining cases that were dropped from that
CL. It also uses the phrasing "invalid operation" instead of "illegal
constant expression" for better consistency with the rest of
cmd/compile and with go/types.
Lastly, this CL extends setconst to recognize failed constant folding
(e.g., division by zero) so that we can properly mark those
expressions as broken rather than continuing forward with bogus values
that might lead to further spurious errors.

This change modifies Value.String() to use the following
representations for non-string values:
<undefined>
<null>
<boolean: true>
<number: 42>
<symbol>
<object>
<function>
It avoids JavaScript conversion semantics in the Go API and lowers the
risk of hidden bugs by unexpected conversions, e.g. the conversion
of the number 42 to the string "42". See discussion in #29642.
This is a breaking change, which are still allowed for syscall/js.
The impact should be small since it only affects uses of
Value.String() with non-string values, which should be uncommon.

ssa/debug_test.go already had a step limit; this exposes
it to individual tests, and it is then set low for the
infinite loop tests.
That however is not enough; in an infinite loop debuggers
see an unchanging line number, and therefore keep trying
until they see a different one. To do this, the concept
of a "bogus" line number is introduced, and on output
single-instruction infinite loops are detected and a
hardware nop with correct line number is inserted into
the loop; the branch itself receives a bogus line number.
This breaks up the endless stream of same line number and
causes both gdb and delve to not hang; Delve complains
about the incorrect line number while gdb does
a sort of odd step-to-nowhere that then steps back
to the loop. Since repeats are suppressed in the reference
file, a single line is shown there.
(The wrong line number mentioned in previous message
was an artifact of debug_test.go, not Delve, and is now
fixed.)
The bogus line number exposed in Delve is less than
wonderful, but compared to hanging, it is better.

Issue #29122 introduced a subtle regression due to the way that

This change adds a special case to the new, optimized TrimSpace to go
back to that behavior. While it is odd behavior and people shouldn't be
relying on these functions returning a nil slice in practice, it's not
worth the breakage of code that does.
This tweak doesn't change the TrimSpace benchmarks significantly.
