When casting between *C.CFTypeRef and *unsafe.Pointer, we used to be
able to do the cast directly. Now with C.CFTypeRef being a uintptr
instead of an unsafe.Pointer, we need an intermediate cast.
Add the insertion of the intermediate cast to the cftype fix module.

cgo uses the presence of these functions to determine whether
a given type is in the CFTypeRef hierarchy and thus should be
a uintptr instead of a pointer. But if the *GetTypeID functions
aren't used by the user code, then they won't be present in the
cgo output, and thus cmd/fix won't see them.
Use the simpler rule that anything ending in *Ref should be
rewritten. This could over-rewrite, but I don't see a simpler
solution. Unlike cgo, it is easy to edit the output to fix any
issues. And fix is a much rarer operation than cgo.
This is a revert of portions of CL 87616.

Cgo currently maps CFTypeRef and its subtypes to unsafe.Pointer
or a pointer to a named empty struct.
However, Darwin sometimes encodes some of CFTypeRef's subtypes as a
few int fields packed in a pointer wrapper. This hackery confuses the
Go runtime as the pointers can look like they point to things that
shouldn't be pointed at.
Switch CFTypeRef and its subtypes to map to uintptr.
Detecting the affected set of types is tricky, there are over 200 of
them, and the set isn't static across Darwin versions. Fortunately,
downcasting from CFTypeRef to a subtype requires calling CFGetTypeID,
getting a CFTypeID token, and comparing that with a known id from a
*GetTypeID() call. So we can find all the type names by detecting all
the *GetTypeID() prototypes and rewriting the corresponding *Ref types
to uintptr. This strategy covers all the cases I've checked and is
unlikely to have a false positive.
Update #23091.

CL 67332 created the fast no-syscall path for time.Now in High Sierra

The cgo checker was issuing an error with cgocheck=2 when a timer
bucket was stored in a pollDesc. The pollDesc values are allocated
using persistentalloc, so they are not in the Go heap. The code is OK
since timer bucket pointers point into a global array, and as such are
never garbage collected or moved.
Mark timersBucket notinheap to avoid the problem. timersBucket values
only occur in the global timers array.

libraries they depend on no longer works.
Now that we have complete deps, change to a simpler scheme in which we
find the shared libraries in the deps, and then use that to sort the

Cut all these off by only applying file change detection to the local package
root: the GOROOT or specific sub-GOPATH in which the package being tested

result will still be used. Don't do that, or else use -count=1.)

Given an inlinable method M in package P:
func (r *MyStruct) M(...) {
When M is compiled within its home package, the source position that
the compiler records for 'r' (receiver parameter variable) is
accurate, whereas if M is built as part of the compilation of some
other package (body read from export data), the declaration line
assigned to 'r' will be the line number of the 'import' directive, not
the source line from M's source file.
This inconsistency can cause differences in the size of abstract
parameter DIEs (due to variable-length encoding), which can then in
turn result in bad abstract origin offsets, which in turn triggers
build failures on iOS (dsymutil crashes when it encounters an
incorrect abstract origin reference).
Work around the problem by removing the "declaration line number"
attribute within the abstract parameter abbreviation table entry. The
decl line attribute doesn't contribute a whole lot to the debugging
experience, and it gets rid of the inconsistencies that trigger the
dsymutil crashes.
