39864980d1 fixes #25446; [FieldDefect] with static: discard cast[pointer](default(pointer)) (#25448) 
fixes #25446

supports this since `static: discard cast[pointer](nil)` works

130eac2f93 fixes #25008; Compiler internal error with static overload (#25234) 
fixes #25008

It seems that `semOverloadedCall` evaluates the same node twice using
`tryConstExpr` in order for `efExplain` to print all the diagnostic
output. The problem is that `tryConstExpr` has side effects, i.e., it
changes the slot index of variables after VM execution.

f009ea6c3e fixes #25208; generates a copy for opcLdConst in the assignments (#25211) 
fixes #25208


```nim
type Conf = object
  val: int

const defaultConf = Conf(val: 123)
static:
  var conf: Conf
  conf = defaultConf
```

```nim
# opcLdConst is now always valid. We produce the necessary copy in the
# assignments now:
```

A `opcLdConst` is generated for `defaultConf` in `conf = defaultConf`.
According to the comment above, we need to handle the copy for
assignments of `opcLdConst`

9ff0333a4c fixes #21353; fixes default closure in the VM (#24070) 
fixes #21353

```nim
  result = newNodeIT(nkTupleConstr, info, t)
  result.add(newNodeIT(nkNilLit, info, t))
  result.add(newNodeIT(nkNilLit, info, t))
```
The old implementation uses `t` which is the type of the closure
function as its type. It is not correct and generates ((nil, nil), (nil,
nil)) for `default(closures)`. This PR creates `(tyPointer, tyPointer)`
for fake closure types just like what cctypes do.

540b414c86 fixes #23925; VM generates wrong cast for negative enum values (#23951) 
Follow up of #23927 which solves the build error.

This is still only a partial fix as it doesn't take into account
unordered enums. I'll make a separate issue for those.

58813a3b2e make all generic aliases tyAlias (#23978) 
fixes #23977

The problem is that for *any* body of a generic declaration,
[semstmts](2e4d344b43/compiler/semstmts.nim (L1610-L1611))
sets the sym of its value to the generic type name, and
[semtypes](2e4d344b43/compiler/semtypes.nim (L2143))
just directly gives the referenced type *specifically* when the
expression is a generic body. I'm blaming `semtypes` here because it's
responsible for the type given but the exact opposite behavior
specifically written in makes me think generating an alias type here
maybe breaks something.

3224337550 give typedesc param nodes type T not typedesc[T] [backport:2.0] (#23115) 
fixes https://github.com/nim-lang/Nim/issues/23112, fixes a mistake in
https://github.com/nim-lang/Nim/pull/22581

This makes `getType(t)` where `t` is a typedesc param with value `T`
equal to `getType(T)`.
