At the end of the codegen pipeline for DXIL we will emit the DXIL into
a global variable in the Module annotated for the "DXIL" section.
This will be used by the MCDXContainerStreamer to emit the DXIL into a
DXContainer DXIL part.
Other parts of the DXContainer will be constructed similarly by
serializing their values into GlobalVariables.
This will allow DXIL to flow into DXContainers through the normal
MCStreamer flow used in the MC layer.
Depends on D122270

A new pass DxilEmitMetadata is added to translate information saved in llvm ir into metadata to match DXIL spec.
Only generate DXIL validator version in this PR.
In llvm ir, validator version is saved in ModuleFlag with "dx.valver" as Key.
!llvm.module.flags = !{!0, !1}
!1 = !{i32 6, !"dx.valver", !2}
!2 = !{i32 1, i32 1}
DXIL validator version has major and minor versions that are specified as named metadata:
!dx.valver = !{!2}
!2 = !{i32 1, i32 7}

A new pass DXILOpLowering was added.
It will scan all llvm intrinsics, create dxil op function if it can map to dxil op function.
Then translate call instructions on the intrinsic into call on dxil op function.
dxil op function will add i32 argument to the begining of args for dxil opcode.
So cannot use setCalledFunction to update the call instruction on intrinsic.
This commit only support sin to start the work.

In supporting opaque pointers we need to re-materialize typed pointers
in bitcode emission. Because of how the value-enumerator pre-allocates
types and instructions we need to insert some no-op bitcasts in the
places that we'll need bitcasts for the pointer types.

The DXIL Prepare pass handles the IR mutations required to convert
modern LLVM IR into something that more closely resembles LLVM-3.7 IR
so that the DXIL bitcode writer can emit 3.7 IR.
This change adds the codegen pass handling the first two IR
transformations:
* stripping new function attributes
* converting fneg into fsub
