Example of vpbroadcast instruction with r32 source operand

The attached is a minimal test to see the bug. When I compiled it on version
2.14.02 (latest stable) using the command line

nasm test_00.nasm -o test_00.obj -l test_00.lst -f win64

I see no error message albeit the third line with vpbroadcastd instruction uses
r32 as its source and is obviously incorrect. Its listing is below:

10 0000000C 62F27D287CD9 vpbroadcastd ymm3, ecx ; this is incorrect (src=r32)
