Trying to load CustomModifiers for runtime field hits an assert

[buyaa-n]

Regex.CompileToAssembly test is failing when the ModulBuilder tries to load custom modifiers for a field:

runtime/src/coreclr/System.Private.CoreLib/src/System/Reflection/RtFieldInfo.cs

Lines 257 to 260 in 7989f18

	public override Type[] GetRequiredCustomModifiers()
	{
	return GetSignature().GetCustomModifiers(1, true);
	}

This call eventually hit assert in:

runtime/src/coreclr/vm/runtimehandles.cpp

Line 1736 in 7989f18

_ASSERTE(parameterIndex == 0);

This doesn't happen locally (64 bit Windows), hits the Assert in some Linux legs and 32 bit windows leg on CI, looks like a bug to me.
