In particular, make it more expensive than breaking after the return
type of a function definition/declaration.
Before:
template <typename T>
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaa<

After:
template <typename T>
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaa<T>::aaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaa);

The current macho linker just copies symbols in section datacoal_nt to
section data, so it doesn't really matter whether or not section
"datacoal_nt" is attached to the global variable.
This is a follow-up to r250370, which made changes in llvm to stop
putting functions and data in the *coal* sections.

If the two operands to an instruction were both
subregisters of the same super register, it would incorrectly
think this counted as the same constant bus use.
This fixes the verifier error in fmin_legacy.ll which
was missing -verify-machineinstrs.

OMPCapturedExprDecl allows caopturing not only of fielddecls, but also
other expressions. It also allows to simplify codegen for several
clauses.

This adds support for finding the dynamic table and dynamic symbol table via
the section table or the program header table. If there's no section table an
attempt is made to figure out the length of the dynamic symbol table.

Separate methods to convert parsed instructions to MCInst:
- VOP3 only instructions (always create modifiers as operands in MCInst)
- VOP2 instrunctions with modifiers (create modifiers as operands
in MCInst when e64 encoding is forced or modifiers are parsed)
- VOP2 instructions without modifiers (do not create modifiers
as operands in MCInst)
- Add VOP3Only flag. Pass HasMods flag to VOP3Common.
- Simplify code that deals with modifiers (-1 is now same as
0). This is no longer needed.
- Add few tests (more will be added separately).
Update error message now correct.

This test isn't posix specific, but it doesn't pass on Windows and is
XFAILed. I suspect that this test, which is expected to fail, is causing
the hangs I'm seeing on our WinASan builder. Moving it to Posix seems
to be the cleanest way to avoid running it on Windows.

We can't do the right thing, since there's no right thing to do, but at
least we can not crash the compiler.

For now, generic virtual registers will not have a register class. We may want
to change that. For instance, if we want to use all the methods from
TargetRegisterInfo with generic virtual registers, we need to either have some
sort of generic register classes that do what we want, or teach those methods
how to deal with nullptr register class.
Although the latter seems easy enough to do, we may still want to differenciate
generic register classes from nullptr to catch cases where nullptr gets
introduced by a bug of some sort.
Anyway, I will file a PR to keep track of that.

Make sure we split ":" from the end of the global function id (which
is <path>:<function> for local functions) instead of the beginning to
avoid splitting at the wrong place for Windows file paths that contain
a ":".

The current function importer will walk the callgraph, importing
transitively any callee that is below the threshold. This can
lead to import very deep which is costly in compile time and not
necessarily beneficial as most of the inline would happen in
imported function and not necessarilly in user code.
The actual factor has been carefully chosen by flipping a coin ;)
Some tuning need to be done (just at the existing limiting threshold).

They don't count for the memory or file size, so this is mostly just a
simplification.
The only noticeable difference should be fewer empty program headers.

Global constructors and destructors are guaranteed to be called
in the order as they appear in a translation unit. So we don't want
to mess up the order if they have the same priority.

Summary:
Just like the existing find_as() method, the new insert_as() accepts
an extra parameter which is used as a key to find the bucket in the
map.
When creating a Constant, we want to check the map before actually
creating the object. In this case we have to perform two queries to
the map, and this extra parameter can save recomputing the hash value
for the second query.

The Use argument was used to compute the operand number for a fast
path when replacing only one operand. However we always have to go
through all the operands. So the argument number can be recomputed
locally anyway.

IMHO this makes the code easier to read and should help with linker
scripts.
This is strongly based on D16575. The main differences are:
We record a range of sections, not every section in a program header.
scanHeaders takes case of deciding what goes in every program header,
including PT_GNU_RELRO
We create dummy sections for the start of the file
With this, program header creation has 3 isolated stages:
Map sections to program headers.
Assign addresses to *sections*
Looking at sections find the address and size of each program header.
Thanks to George Rimar for the initial version.

short option as an aid to memory. Like it's w because of the W in throW.
That helps me remember. If we are going to take these out we should take them
all out. But I kind of like them.

It looks like clang has a couple of test cases which caught the fact LVI was not slightly more precise after 260439. When looking at the failures, it struck me as wasteful to be querying nullness of a constant via LVI, so instead of tweaking the clang tests, let's just stop querying constants from this source.
