1324d2e04c Asm syntax pragma (#23119)
(Inspired by this pragma in nir asm PR)

`inlineAsmSyntax` pragma allowing specify target inline assembler syntax
in `asm` stmt.

It prevents compiling code with different of the target CC inline asm
syntax, i.e. it will not allow gcc inline asm code to be compiled with
vcc.

```nim
proc nothing() =
  asm {.inlineAsmSyntax: "gcc".} """
    nop
  """
```

The current C(C++) backend implementation cannot generate code for gcc
and for vcc at the same time. For example, `{.inlineAsmSyntax: "vcc".}`
with the ICC compiler will not generate code with intel asm syntax, even
though ICC can use both gcc-like asm and vcc-like. For implement support
for gcc and for vcc at the same time in ICC compiler, we need to
refactor extccomp

5717a4843d fixes #22676; remove wMerge which is a noop for more than 8 years (#22678)
fixes #22676

If csource or CI forbids it, we can always fall back to adding it to the
nonPragmaWords list. I doubt it was used outside of the system since it
was used to implement & or something for magics.

2cca38d33c pragma for sfCallsite instead of name check + better semantics, test (#20464)
* pragma for sfCallsite instead of name check at every template definition

Not documented because it seems to be for internal use?

Should also make it possible to make comparisons and setops imports, but this doesn't have to be done.

I can reuse a name like `cursor` for the pragma as well, added a new name just to be safe.

14656154ef Add doctype: RST|Markdown|RstMarkdown pragma (#20252)
* Add `doctype: RST|Markdown|RstMarkdown` pragma

Implements https://github.com/nim-lang/RFCs/issues/68 ,
see also discussion in https://github.com/nim-lang/Nim/issues/17987

The permitted values:
* `markdown`, which is default. It still contains nearly all of
  the RST supported but it is assumed that in time we will give up
  most or all RST features in this mode
* `rst`, without any extensions
* `RstMarkdown` — compatibility with Nim 1.x. It's basically RST
  with those Markdown features enabled that don't conflict with RST.

* Apply suggestions from code review

Co-authored-by: Clay Sweetser <Varriount@users.noreply.github.com>

* Additional fix in spirit of review

* Fix test after #20188

800cb006e7 Change styleCheck to ignore foreign packages (#19822)
* Change `styleCheck` to ignore foreign packages

* Symbols from foreign packages are now ignored.
* Fixed `styleCheck` violations in `compiler` package.
* Added symbol ownership to custom annotation pragmas.
* Minor refactors to cleanup style check callsites.
* Minor internal documentation of reasons why a symbol isn't checked.

Style violations were fixed in the compiler after thet were exposed by
the changes. The compiler wouldn't compile otherwise.

Symbol ownership for custom pragma annotations is needed for checking
the annotation's style. A NPE was raised otherwise.

Fixes #10201
See also nim-lang/RFCs#456

* Fix a misunderstanding about excluding field style checks

I had refactored the callsites of `styleCheckUse` to apply the DRY
principle, but I misunderstood the field access handling in a template
as a general case. This corrects it.

* Fix some `styleCheck` violations in `compiler/evalffi`

The violations were exposed in CI when the compiler was built with
libffi.

* Removed some uneeded transitionary code

* Add changelog entry
