Summary: Move and correct LLVMDIBuilderCreateTypedef. This is the last API in DIBuilderBindings.h, so it is being removed and the C API will now be re-exported from IRBindings.h.

Summary: Fixes the bots - I moved LLVMSetSubprogram into the DIBuilder bindings, so the Go bindings need to move as well.

This patch adds a set of unstable C API bindings to the DIBuilder interface for
creating structure, function, and aggregate types.
This patch also removes the existing implementations of these functions from
the Go bindings and updates the Go API to fit the new C APIs.

X86 Supports Indirect Branch Tracking (IBT) as part of Control-Flow Enforcement Technology (CET).
IBT instruments ENDBR instructions used to specify valid targets of indirect call / jmp.
The `nocf_check` attribute has two roles in the context of X86 IBT technology:
1. Appertains to a function - do not add ENDBR instruction at the beginning of the function.
2. Appertains to a function pointer - do not track the target function of this pointer by adding nocf_check prefix to the indirect-call instruction.
This patch implements `nocf_check` context for Indirect Branch Tracking.
It also auto generates `nocf_check` prefixes before indirect branchs to jump tables that are guarded by range checks.

By this change, building a Go code with LLVM Go bindings causes a compilation error as follows.
go build llvm.org/llvm/bindings/go/llvm: invalid flag in #cgo LDFLAGS: -Wl,-headerpad_max_install_names
llvm-go tool generates cgo LDFLAGS directive from `llvm-config --ldflags` and it contains -Wl,option options. But -Wl,option is banned by default. To avoid this problem, we need to set $CGO_LDFLAGS_ALLOW environment variable to notify a compiler that the flags should be allowed.
$ export CGO_LDFLAGS_ALLOW='-Wl,(-search_paths_first|-headerpad_max_install_names)'
By default for go 1.10 and go 1.9.5 these options should appear in the accepted set of options, however, if you're running into the error it's useful to have this documented.

Summary:
This seems like an uncontroversial first step toward providing access to the metadata hierarchy that now exists in LLVM. This should allow for good debug info support from C.
Future plans are to deprecate API that take mixed bags of values and metadata (mainly the LLVMMDNode family of functions) and migrate the rest toward the use of LLVMMetadataRef.
Once this is in place, mapping of DIBuilder will be able to start.

Summary:
Currently Go binding only has SetCurrentDebugLocation method.
I added GetCurrentDebugLocation method to IRBuilder instance.
I added this because I want to save current debug location, change debug location temporary and restore the saved one finally.
This is useful when source location jumps and goes back after while LLVM IR generation.
I also added tests for this to ir_test.go.
I confirmed that all test passed with this patch based on r298890

Summary:
LLVMGetTargetDataLayout was removed from the C API,
and then TargetMachine.TargetData was removed. Later,
LLVMCreateTargetMachineData was added to the C API,
and we now expose this via the Go API.

LLVMGetTargetMachineData has been removed, and LLVMGetDataLayout is

This deprecates:
* LLVMParseBitcode
* LLVMParseBitcodeInContext
* LLVMGetBitcodeModuleInContext
* LLVMGetBitcodeModule
They are replaced with the functions with a 2 suffix which do not record
a diagnostic.

Type specific declarations have been moved to Type.h and error handling
routines have been moved to ErrorHandling.h. Both are included in Core.h
so nothing should change for projects directly including the headers,
but transitive dependencies may be affected.

Previously, subprograms contained a metadata reference to the function they
described. Because most clients need to get or set a subprogram for a given
function rather than the other way around, this created unneeded inefficiency.
For example, many passes needed to call the function llvm::makeSubprogramMap()
to build a mapping from functions to subprograms, and the IR linker needed to
fix up function references in a way that caused quadratic complexity in the IR
linking phase of LTO.
This change reverses the direction of the edge by storing the subprogram as
function-level metadata and removing DISubprogram's function field.
Since this is an IR change, a bitcode upgrade has been provided.
Fixes PR23367. An upgrade script for textual IR for out-of-tree clients is
attached to the PR.
