JIT: stack walk failure in arm64 function fragments #91139
Description
Compile: TestClass156-test-assertion.cs.txt
Run on osx arm64 with
export COMPlus_JitAggressiveInlining=1
export COMPlus_JitSplitFunctionSize=100
export COMPlus_GCStress=0x4
Assert failure(PID 94626 [0x000171a2], Thread: 23328476 [0x163f6dc]): !"About to FailFast. set DOTNET_AssertOnFailFast=0 if this is expected"

(may also repro on other arm64 hosts, did not try)
By increasing the split function size you can make the test "pass":
export COMPlus_JitAggressiveInlining=1
export COMPlus_JitSplitFunctionSize=138
export COMPlus_GCStress=0x4
Unhandled exception. System.OverflowException: Value was either too large or too small for a Decimal.
