Remove pointless unsafe block in CilAssembler.cs

ILAssembler/src/ILAssembler/CilAssembler.cs

Lines 244 to 254 in ccdac27

	byte* rawSignature = stackalloc byte[encoder.Builder.Count];
	byte* c = rawSignature;
	foreach (Blob blob in blobEncoder.Builder.GetBlobs())
	{
	foreach (byte b in blob.GetBytes())
	{
	*c++ = b;
	}
	}
	_context.ILInfo.SetLocalSignature(rawSignature, blobEncoder.Builder.Count);

Saves one minor heap allocation every assemble, but not really worth the readability loss and the stackalloc doesn't guard against stack overflow.
