[coroutines] Adding builtins for coroutine intrinsics and backendutil support. Summary: With this commit simple coroutines can be created in plain C using coroutine builtins.

[coroutines] Replace all coro.frame builtins with an SSA value of coro.begin SemaCoroutine forms expressions referring to the coroutine frame of the enclosing coroutine using coro.frame builtin. During codegen, we emit llvm.coro.begin intrinsic that returns the address of the coroutine frame. When coro.frame is emitted, we replace it with SSA value of coro.begin. llvm-svn: 303598

[coroutines] Add __builtin_coro_noop => llvm.coro.noop A recent addition to Coroutines TS (https://wg21.link/p0913) adds a pre-defined coroutine noop_coroutine that does nothing. To implement this feature, we implemented an llvm.coro.noop intrinsic that returns a coroutine handle to a coroutine that does nothing when resumed or destroyed. This patch adds a builtin __builtin_coro_noop() that maps to llvm.coro.noop intrinsic. Related llvm change: https://reviews.llvm.org/D45114 llvm-svn: 328993
