bors 11f838d64a Auto merge of #81978 - tmiasko:head-ctor, r=Mark-Simulacrum
Inline hot part of PatStack::head_ctor

When building rustc with `-Codegen-units=1` this inline hint ensures
that obtaining already initialized head constructor does not involve
a function call overhead and reduces the instruction count in
match-stress-enum-check full benchmark from 11.9G to 9.8G.

It shouldn't have significant impact on the currently default
configuration where it reflects existing inlining decisions.
