<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Improve error messages for (a %m) without LinearTypes
Detect when the user forgets to enable the LinearTypes
extension and produce a better error message.
Steals the (a %m) syntax from TypeOperators, the workaround
is to write (a % m) instead.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Workaround for #18623: GHC crashes bc. under rlimit for vmem it will reserve
_all_ of it, leaving nothing for, e.g., thread stacks.
Fix will only allocate 2/3rds and check whether remainder is at least large
enough for minimum amount of thread stacks.
