Add parts of an assert back

[jakobbotsch]

Under JitRepeatOpts we sometimes turn early-arg stores into GT_NOP
nodes.

Fix #68472 (the test there runs under JitRepeatOpts=*).

This assert can be removed in #68460 again.

Fix #68472 (the test there runs under JitRepeatOpts=*).

The PGO runs don't use JitRepeatOpts.

[jakobbotsch]

The PGO runs don't use JitRepeatOpts.

The failing test is Runtime_56953 which sets it for all methods in its .csproj file:

runtime/src/tests/JIT/Regression/JitBlue/Runtime_56953/Runtime_56953.csproj

Lines 10 to 17 in 1958c7e

	<CLRTestBatchPreCommands><![CDATA[
	$(CLRTestBatchPreCommands)
	set COMPlus_JitOptRepeat=*
	]]></CLRTestBatchPreCommands>
	<BashCLRTestPreCommands><![CDATA[
	$(BashCLRTestPreCommands)
	export COMPlus_JitOptRepeat=*
	]]></BashCLRTestPreCommands>

This combined with COMPlus_ReadyToRun=0 hits the problem in a few methods in SPC.
