Issue: Crash when compiling in `dev` profile but not `release` while doing intensive floating-point math: `_ZN4llvm16DwarfCompileUnit25createAndAddScopeChildrenEPNS_12LexicalScopeERNS_3DIEE+0x702`

<!--
Thank you for filing a bug report! 🐛 Please provide a short summary of the bug,
along with any information you feel relevant to replicating the bug.
-->

I tried this code, which came from a modified version of the `numintsynth.py` script of @raphlinus' `spiro` project:

https://gist.github.com/ctrlcctrlv/4007872ebc7bdac4f6c3e33051bef8d9

Don't be discouraged by the fact it is ≈5000 lines, it comes from a Python script, to wit:

https://gist.github.com/ctrlcctrlv/bdcab4072a5862ef7c4e9f2a779bdbb4

I expected to see this happen: a successful compilation

Instead, this happened: `rustc` crashed.

This might be a bug in llvm. The crash seems to blame the function https://llvm.org/doxygen/DwarfCompileUnit_8cpp_source.html#l01051 ```DIE *DwarfCompileUnit::createAndAddScopeChildren(LexicalScope *Scope, DIE &ScopeDIE)``` ultimately.
