Subject: [PATCH] clang/arm: Do not use MUST_TAIL_CALL

This causes clang-17 to crash see [1]
this code is new in webkit 2.42[2] thats why we do not see the crash in older webkit

[1] https://github.com/llvm/llvm-project/issues/67767
[2] https://github.com/WebKit/WebKit/commit/4d816460b765acd8aef90ab474615850b91ecc35

Upstream-Status: Inappropriate [work around to avoid clang compiler crash]
