static LongJitType generateSExtIntToLong(MethodVisitor mv) {
		mv.visitInsn(I2L);
		return LongJitType.I8;
	}
Convert a signed {@link IntJitType#I4 int4} to {@link LongJitType#I8 int8}.

<p>
Note that if conversion from a smaller int type is needed, the generator must first call
{@link #generateSExt(JitType, MethodVisitor)}.

@param mv the method visitor
@return the resulting type ({@link LongJitType#I8 int8})
