DAG: Fix creating select with wrong condition type
This code added in r297930 assumed that it could create
a select with a condition type that is just an integer
bitcast of the selected type. For AMDGPU any vselect is
going to be scalarized (although the vector types are legal),
and all select conditions must be i1 (the same as getSetCCResultType).
This logic doesn't really make sense to me, but there's
never really been a consistent policy in what the select
condition mask type is supposed to be. Try to extend
the logic for skipping the transform for condition types
that aren't setccs. It doesn't seem quite right to me though,
but checking conditions that seem more sensible (like whether the
vselect is going to be expanded) doesn't work since this
seems to depend on that also.

[IRCE] Fix intersection between signed and unsigned ranges
IRCE for unsigned latch conditions was temporarily disabled by rL314881. The motivating
example contained an unsigned latch condition and a signed range check. One of the safe
iteration ranges was `[1, SINT_MAX + 1]`. Its right border was incorrectly interpreted as a negative
value in `IntersectRange` function, this lead to a miscompile under which we deleted a range check
without inserting a postloop where it was needed.
This patch brings back IRCE for unsigned latch conditions. Now we treat range intersection more
carefully. If the latch condition was unsigned, we only try to consider a range check for deletion if:
1. The range check is also unsigned, or
2. Safe iteration range of the range check lies within `[0, SINT_MAX]`.
The same is done for signed latch.
Values from `[0, SINT_MAX]` are unambiguous, these values are non-negative under any interpretation,
and all values of a range intersected with such range are also non-negative.
We also use signed/unsigned min/max functions for range intersection depending on type of the
latch condition.

[IRCE] Smarter detection of empty ranges using SCEV
For a SCEV range, this patch replaces the naive emptiness check for SCEV ranges
which looks like `Begin == End` with a SCEV check. The range is guaranteed to be
empty of `Begin >= End`. We should filter such ranges out and do not try to perform
IRCE for them.
For example, we can get such range when intersecting range `[A, B)` and `[C, D)`
where `A < B < C < D`. The resulting range is `[max(A, C), min(B, D)) = [C, B)`.
This range is empty, but its `Begin` does not match with `End`.
Making IRCE for an empty range is basically safe but unprofitable because we
never actually get into the main loop where the range checks are supposed to
be eliminated. This patch uses SCEV mechanisms to treat loops with proved
`Begin >= End` as empty.

[COFF] Clean up boolean flag handling
LLD's handling of boolean flags is suboptimal:
* All boolean flags have a corresponding `:no` flag to turn the flag
off, and the linker should scan for both the non-suffixed and suffixed
flags (and the last one should win), but right now it only scans for
either the suffixed or non-suffixed flag (depending on the default
flag value).
* The `B` multiclass only allows specifying help text for the suffixed
(`:no`) flag, but for some flags (e.g. `/appcontainer`) the help text
should be associated with the non-suffixed flag instead.
Extend the `B` multiclass to have help text for both non-suffixed and
suffixed flag variants, and alter the existing help text accordingly in
some cases. Scan for both the non-suffixed and suffixed variants in the
driver and set config values accordingly.
This should mostly have no behavior change, apart from the added help
text and the modified argument scanning. Some flags are handled slightly
differently now, however; for example, LLD would previously always treat
64-bit images as large address aware, whereas `/largeaddressaware:no` is
now respected for 64-bit images (which is also how link.exe behaves).

We used the scheduling information retrieved from the Broadwell architects in order to create the file.
The scheduling information includes latency, number of micro-Ops and used ports by each BDW instruction.
The patch continues the scheduling replacement and insertion effort started with the SandyBridge (SNB) target in r310792, the Haswell (HSW) target in r311879, the SkylakeClient (SKL) target in rL313613 + rL315978 and the SkylakeServer (SKX) in rL315175.
Performance fluctuations may be expected due to code alignment effects.

[llvm-cov] Use a stable sort on sub-views
We need to use a stable sort on instantiation and expansion sub-views to
produce consistent output. Fortunately, we've gotten lucky and the tests
have checks for the stable order.
This is needed to unblock D39245. Once that lands, we'll have better
test coverage for sort non-determinism.

Summary:
Similar to NetBSD, in FreeBSD, the first returned entry when callbacks
are done via dl_iterate_phdr will return the main program. Ignore that

MIR: Print the register class or bank in vreg defs
This updates the MIRPrinter to include the regclass when printing
virtual register defs, which is already valid syntax for the
parser. That is, given 64 bit %0 and %1 in a "gpr" regbank,
%1(s64) = COPY %0(s64)
would now be written as
%1:gpr(s64) = COPY %0(s64)
While this change alone introduces a bit of redundancy with the
registers block, it allows us to update the tests to be more concise
and understandable and brings us closer to being able to remove the
registers block completely.
Note: We generally only print the class in defs, but there is one
exception. If there are uses without any defs whatsoever, we'll print
the class on all uses. I'm not completely convinced this comes up in
meaningful machine IR, but for now the MIRParser and MachineVerifier
both accept that kind of stuff, so we don't want to have a situation
where we can print something we can't parse.

[refactor] Initial outline of implementation of "extract function" refactoring
This commit adds an initial, skeleton outline of the "extract function"
refactoring. The extracted function doesn't capture variables / rewrite code
yet, it just basically does a simple copy-paste.
The following initiation rules are specified:
- extraction can only be done for executable code in a function/method/block.
This means that you can't extract a global variable initialize into a function
right now.
- simple literals and references are not extractable.
This commit also adds support for full source ranges to clang-refactor's test
mode.
