Only allow string mutation that is certain not to require string data to
be resized and reallocated: writing bytes into a unibyte string, and
changing ASCII to ASCII in a multibyte string.
This ensures that mutation will never transform a unibyte string to
multibyte, that the size of a string in bytes never changes, and that
the byte offsets of characters remain the same. Most importantly, it
removes a long-standing obstacle to reform of string representation and
allow for future performance improvements.

The code to automatically fallback to margins is not correct: it
relies implicitly on the buffer being displayed in a window
while flymake-mode is running. If the buffer is created while
not displayed, we will always automatically fallback to margins,
which is incorrect.
Avoid the regression by simply disabling this code. I'll try
again to fall back automatically in the future. (Bug#79244)

about automatic fallback to margins.

Currently, a hard-coded set of macros is automatically expanded
during generation of autoloads. To allow user macros to request
such expansion, this implements a new declare form
`autoload-macro' (Bug#78995), with supported value `expand'.
For example, macros which wrap `define-minor-mode', can declare
`(autoload-macro expand)' to request that ;;;###autoload-adorned
calls to the macro are expanded during generation, such that an
autoload for the resulting function is created.
* lisp/emacs-lisp/byte-run.el (byte-run--set-autoload-macro):

declare forms.

Handle the `autoload-macro=expand' property for macros. Load
the ;;;###autoload-containing file if an unknown symbol is
encountered in the car of the following form, to give packages a
chance to define their macros and request expansion. Factor
list of special function-defining macros out as a constant
variable: `loaddefs--defining-macros'.
