This aligns the multiple exit costing with all the other cost decisions. Note that UnrollAndJam, which is the only other caller of the original home of this code, unconditionally bails out of multiple exit loops.
The new -mtargetos= option is a replacement for the existing, OS-specific options
like -miphoneos-version-min=. This allows us to introduce support for new darwin OSes
easier as they won't require the use of a new option. The older options will be
deprecated and the use of the new option will be encouraged instead.

In some environments this test could fail if start.S has its own DWARF
CompileUnit or similar are included before the DWARF CompileUnit for the
file.
This change makes the test independent of the index of the compile unit,
instead checking the filename.

The .cpp file uses SIGNAL_POLLING_UNSUPPORTED to guard the call
to sigaction, so use it in the .h file too. (LLVM also calls
sigaction without a guard on non-Windows.)
No behavior change.

The option to not preserve LCSSA is in fact not tested at all in upstream. I was tempted to just remove the code entirely, but realized I didn't need to for my actual goal.
Dummy procedures can be defined as subprograms with explicit
interfaces, e.g.
subroutine subr(dummy)
interface
subroutine dummy(x)
real :: x
end subroutine
end interface
! ...
end subroutine
but the symbol table had no means of marking such symbols as dummy
arguments, so predicates like IsDummy(dummy) would fail. Add an
isDummy_ flag to SubprogramNameDetails, analogous to the corresponding
flag in EntityDetails, and set/test it as needed.

When we build with split dwarf in single mode the .o files that contain both "normal" debug sections and dwo sections, along with relocaiton sections for "normal" debug sections.
When we create DWARF context in DWARFObjInMemory we process relocations and store them in the map for .debug_info, etc section.
For DWO Context we also do it for non dwo dwarf sections. Which I believe is not necessary. This leads to a lot of memory being wasted. We observed 70GB extra memory being used.
I went with context sensitive approach, flag is passed in. I am not sure if it's always safe not to process relocations for regular debug sections if Obj contains .dwo sections.
If it is alternatvie might be just to scan, in constructor, sections and if there are .dwo sections not to process regular debug ones.

Add new pass LowerRefTypesIntPtrConv to generate trap

This patch updates VPInterleaveRecipe::print to print the actual defined
VPValues for load groups and the store VPValue operands for store
groups.
The IR references may become outdated while transforming the VPlan and
the defined and stored VPValues always are up-to-date.

Currently, OR1K architecture put the program counter at offset 0x128 of
the current `or1k_thread_state_t`. However, the PC is restored after
updating the thread pointer in `r3`, which causes the PC to be fetched
incorrectly.
This patch swaps the order of restoration of `r9` and `r3`, such that
the PC is restored to `r9` using the current thread state.

In some cases, when the execution path of the diagnostic
goes back and forth, arrows can overlap and create a mess.
Dimming arrows that are not relevant at the moment, solves this issue.
They are still visible, but don't draw too much attention.

This commit adds a very first version of this feature.
It is off by default and has to be turned on by checking the
corresponding box. For this reason, HTML reports still keep
control notes (aka grey bubbles).
Further on, we plan on attaching arrows to events and having all arrows
not related to a currently selected event barely visible. This will
help with reports where control flow goes back and forth (eg in loops).
Right now, it can get pretty crammed with all the arrows.

Definition of `__cpp_threadsafe_static_init` macro is controlled by
language option Opts.ThreadsafeStatics. This patch sets language
option to false by default in OpenCL mode, resulting in macro
`__cpp_threadsafe_static_init` being undefined. Default value can be
overridden using command line option -fthreadsafe-statics.
Change is supposed to address portability because not all OpenCL
vendors support thread safe implementation of static initialization.
