Summary:
Prior to this patch, OpenCL code such as the following would attempt to create
a BranchInst with a non-bool argument:
if (enqueue_kernel(get_default_queue(), 0, nd, ^(void){})) /* ... */
This patch is a follow up on a similar issue with pipe builtin
operations. See commit r280800 and https://bugs.llvm.org/show_bug.cgi?id=30219.
This change, while being conservative on non-builtin functions,
should set the type of expressions invoking builtins to the
proper type, instead of defaulting to `bool` and requiring
manual overrides in Sema::CheckBuiltinFunctionCall.
In addition to tests for enqueue_kernel, the tests are extended to
check other OpenCL builtins.
