Auto merge of #112240 - cjgillot:recurse-inline, r=scottmcm

Browse Source 
Only check inlining counter after recursing.

This PR aims to reduce the strength of https://github.com/rust-lang/rust/pull/105119 even more.

In the current implementation, we check the inline count before recursing. This means that we never actually reach inlining depth 3.

This PR checks the counter after recursion, to give a chance to inline at depth >= 3.
