This was intended to be a generic CMake solution to a problem
shared across several projects.  It turns out it doesn't interact
very well certain CMake configurations, and furthermore the
"problem" is actually not a problem, as the problematic code
is never executed to begin with.  So this really isn't solving
anything.

The isShared case was handled by the isInCurrentDSO check.

We're seeing strange issues on the public GreenDragon Darwin bots which
we don't understand. x86_64h tests are still being run on pre-Haswell
bots despite the added checks in test/ubsan_minimal/lit.common.cfg,
which were verified on our internal bots.

I'm unable to ssh into the affected public bot, so for now am trying a
more aggressive check which disables all x86_64h testing for
ubsan-minimal on Darwin.

Arg instances can be claimed. After claimed, its `isClaimed` function
returns true. We do not use that notion in lld, so using NoClaim
versions of functions is just confusing. This patch is to just use
hasArg instead of hasArgNoClaim.

Used incorrect types for target specific parameters in debug mode,
should use original pointers rather than the pointee types.

Summary:
Full inline cost is computed when -inline-cost-full is true or ORE is
non-null. This patch adds another way to compute full inline cost by
adding a field to InlineParams. This will be used by SampleProfileLoader
to check legality of inlining a callee that it wants to inline.

These are changes to reduce redundant computations when calculating a
feasible vectorization factor:
1. early return when target has no vector registers
2. don't compute register usage for the default VF.

Suggested during review for D37702.

This is how the flag is documented in GNU binutils ld; -Bstatic

In MinGW configurations (GCC, or clang with a *-windows-gnu target),
the -export directives in the object file contains the undecorated
symbol name, while it is decorated in MSVC configurations. (On the
command line, link.exe takes an undecorated symbol name for the
-export argument though.)

Summary:
Added text options to -pgo-view-counts and -pgo-view-raw-counts that dump block frequency and branch probability info in text.

This is useful when the graph is very large and complex (the dot command crashes, lines/edges too close to tell apart, hard to navigate without textual search) or simply when text is preferred.

We were previously handling aliases during dead stripping by adding
the aliased global's "original name" GUID to the worklist. This will
lead to incorrect behaviour if the global has local linkage because
the original name GUID will not correspond to the global's GUID in
the summary.

Because an alias is just another name for the global that it
references, there is no need to mark the referenced global as used,
or to follow references from any other copies of the global. So all
we need to do is to follow references from the aliasee's summary
instead of the alias.

Summary:
Change the type of the Redirects parameter of llvm::sys::ExecuteAndWait,
ExecuteNoWait and other APIs that wrap them from `const StringRef **` to
`ArrayRef<Optional<StringRef>>`, which is safer and simplifies the use of these
APIs (no more local StringRef variables just to get a pointer to).

Corresponding clang changes will be posted as a separate patch.
