[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).

[Sema] Document+test the -Wsign-compare change for enums in C code [NFC]
rL316268 / D39122 has fixed PR35009, and now when in C,
these three(?) diagnostics properly use the enum's underlying
datatype.
While it was fixed, the test coverage was clearly insufficient,
because the -Wsign-compare change didn't show up in any of the
tests, until it was reported in the post-commit mail for rL316268.
So add the test for the -Wsign-compare diagnostic for enum
for C code, and while there, document this in the release notes.
The fix itself was obviously correct, so unless we want to silence
this new diagnosed case, i deem this commit to be NFC.

Adding the scheduling information for the Browadwell (BDW) CPU target.
This patch adds the instruction scheduling information for the Broadwell (BDW) architecture target by adding the file X86SchedBroadwell.td located under the X86 Target.
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.
