`{.push overflowChecks: off.}` works in backends. Though it could be
implemented as a magic function.
By inspecting the generated C code, the overflow check is eliminated in
the debug or release mode.
Likewise, the index checking is probably not needed.

Checking if there's any side-effects and if just changing typeRel is
adequate for this issue before trying to look into related ones.
`skipBoth` is also not that great, it can lead to code that works
sometimes but fails when the proc is instantiated with branching
aliases. This is mostly an issue with error clarity though.

fixes#22639 for the third time
Nodes generated by `getType` for `tyGenericInst` types, instead of
having the original `tyGenericInst` type, will have the type of the last
child (due to the `mapTypeToAst` calls which set the type to the given
argument). This will cause subsequent `getType` calls to lose
information and think it's OK to use the sym of the instantiated type
rather than fully expand the generic instantiation.
To prevent this, update the type of the node from the `mapTypeToAst`
calls to the full generic instantiation type.

fixes#22598, properly fixes#21887 and fixes test case issue number
When an enum field sym choice has to choose a type, check if its name is
ambiguous in the local scope, then check if the first symbol found in
the local scope is the first symbol in the sym choice. If so, choose
that symbol. Otherwise, give an ambiguous identifier error.
The dependence on the local scope implies this will always give
ambiguity errors for unpicked enum symchoices from generics and
templates and macros from other scopes. We can change `not
isAmbiguous(...) and foundSym == first` to `not (isAmbiguous(...) and
foundSym == first)` to make it so they never give ambiguity errors, and
always pick the first symbol in the symchoice. I can do this if this is
preferred, but no code from CI seems affected.

## Future work
We should turn all the error nodes into nodes of a nkError kind, which
could be a industrious task. But perhaps we can add a special treatment
for error nodes to make the transition smooth.

Current knowledge:
- delaying cache fixes the issue
- changing return of `if inst.len < key.len:` in `searchInstTypes` to
`continue` fixes the issue. With return the broken types are also cached
over and over
Related issues are completely unaffected as of now, so there must be
something deeper.
I am also still trying to find the true cause, so feel free to ignore
for now
