wrong order of bits in bit fields #307

@AndreaOrru

Description

@AndreaOrru
const VGAEntry = packed struct {
    c:  u8,
    fg: u4,
    bg: u4,
};

Expected bit layout as implemented by C compilers (c = char bits, b = bg bits, f = fg bits):
cccccccc bbbbffff

Zig produces this instead:
cccccccc ffffbbbb

Is this expected behavior?
