dxcompiler produces raw bitcode module when validation is disabled #6

Description

@dmpots

When validation is disabled (via /Vd on the dxc command line) the output is a plain llvm bitcode module instead of a dxil container. I would expect the output to be a dxil container with unsigned dxil inside.

λ dxc  t.hlsl /Fo t.fxc /Tps_5_0
λ file t.fxc
t.fxc: data
λ Powershell -Command "Get-Content t.fxc -Encoding Byte -TotalCount 4 | Format-Hex"
