* fix#15939, fix#15464 VM now supports `addr(mystring[ind])` (index + index assignment), var char return etc
* cleanups
* cstring tests
* add test for bug #15464
* improve test coverage
* ORC: prepare for another patent-pending optimization
* bugfix
* '=copy' for refs can take a cyclic parameter for more ORC optimizations
* ORC: exploit the common 'it = it.next' pattern
* can't hurt to check for nil
* use an algorithm that is not obviously broken
* restore the test case
* final cleanups for --gc:orc
* doAssertRaises now correctly handles foreign exceptions; now shows which exception is raised on mismatch
* nimscript now handles `Exception as e`
* remove catch-all doAssertRaises overload from this PR

* new: `nim -i cmd`
* rename -i to -e (for eval); consistent with majority of other programing languages
* `nim e -e:cmd` now works; bugfix: `echo cmd | nim e -` now works
* honor --betterRun
* address comments
* --eval alias for -e (replaces undocumented --eval which was a noop)
* --eval now defaults to e (nimscript) instead of r
* address comment: remove -e, only keep --eval
* address comment
* fixup
* Update compiler/nimconf.nim

Add a macro `enumLen` which is used to determine the number of items in
an enumeration type to the `typetraits.nim` module. Also, add unit tests
for it in the `ttypetraits.nim` module.
Related to nimlang/Nim#15824
Make `requiresInit` pragma to work for distinct types in addition to
objects. Tagging of distinct types with `requiresInit` pragma was
already supported, but its impact wasn't applied. Now its behavior when
applied on distinct types is as follows.
Given the following distinct type definitions:
```nim
type
DistinctObject {.requiresInit, borrow: `.`.} = distinct MyObject
DistinctString {.requiresInit.} = distinct string
```
The following code blocks will fail to compile:
```nim
var foo: DistinctFoo
foo.x = "test"
doAssert foo.x == "test"
```
```nim
var s: DistinctString
s = "test"
doAssert s == "test"
```
But these ones will compile successfully:
```nim
let foo = DistinctFoo(Foo(x: "test"))
doAssert foo.x == "test"
```
```nim
let s = "test"
doAssert s == "test"
```
* add parseEnumRange
* fix runnable example
* update changelog
* use parseEnumRange in compiler

* Tmp -> Temp
* Fixed runnableExamples on windows
* changelog.md: Group the new `to` procs [ci skip]
This also moves the `critbits.toCritBitTree` entry from the "Language
Changes" section to the "Standard library additions and changes"
section.
