Revert "[CostModel] Unify Intrinsic Costs."

This reverts commit de71def3f59dc9f12f67141b5040d8e15c84d08a.

This is causing some very large changes, so I'm first going to break
this patch down and re-commit in parts.

[CostModel] Sink intrinsic costs to base TTI.

Recommitting part of "[CostModel] Unify Intrinsic Costs."
de71def3f59dc9f12f67141b5040d8e15c84d08a

Move the switch statement from TTImpl::getIntrinsicCost to
TTI::getIntrinsicInstrCost. This enables BasicTTI to understand
more 'free' intrinsics instead of defaulting to a cost of 1.

Commit 79e5ecfa7a6c19ff08d39664bd30f72ab6e4f940 by james.henderson
On Windows, handle interrupt signals without crash message

For LLVM on *nix systems, the signal handlers are not run on signals
such as SIGINT due to CTRL-C. See sys::CleanupOnSignal. This makes
sense, as such signals are not really crashes. Prior to this change,
this wasn't the case on Windows, however. This patch changes the Windows
behaviour to be consistent with Linux, and adds testing that verifies
this.

The test uses llvm-symbolizer, but any tool with an interactive mode
would do the job.

Fix compile for -DLIBCXX_BUILD_EXTERNAL_THREAD_LIBRARY

Summary: Compilation with  -DLIBCXX_BUILD_EXTERNAL_THREAD_LIBRARY was failing due to missing declarations of functions used in libcxx/include/atomic. The lines this commit affects are the places where those functions are defined, now moved to be always defined.

Fix debug info for NoDebug attr

NoDebug attr does not totally eliminate debug info about a function when
inlining is enabled. This is inconsistent with when inlining is disabled.

This patch fixes that.
