Implement salavageDebugInfo functionality for SelectionDAG.
Similar to how llvm::salvagDebugInfo hooks into InstCombine, this adds
a hook that can be invoked before an SDNode that is associated with an
SDDbgValue is erased to capture the effect of the deleted node in a
DIExpression.
The motivating example is an SDDebugValue attached to an ADD operation
that gets folded into a LOAD+OFFSET operation.

[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).

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.

Revert "[lldbtests] Handle errors instead of crashing."
The commit breaks the case where you specify just a filename to the
compiler. Previously, it would look up the compiler in your path, now it
complains that the compiler is not found. One of the lldb buildbots is
depending on this. It seems like a nice feature to have, as it means
less typing and being able to avoid hard-coding the system compiler path
in the bot config.
This reverts commit r316393.

[utils] make retq/retl regex an option that is off by default
Ideally, we should compare 32- and 64-bit versions to see if the
ret line is the only difference and then insert the regex only
in that case. But this is a quick hack to avoid a bunch of noise
as existing tests are updated.

[ARM] Tighten up CHECK lines in a test
These tests checked for the line number without a leading ":", so for example,
a missed diagnostic on line 123 could match one on line 1123, 2123, etc,
desynchronising the test for hundreds of lines.
This couldn't cause it to incorrectly pass or fail, but made it hard to track
down test failures.

Do not add a colon chunk to the code completion of class inheritance access modifiers
With enabled CINDEXTEST_CODE_COMPLETE_PATTERNS env option (which enables
IncludeCodePatterns in completion options) code completion after colon
currently suggests access modifiers with 2 completion chunks which is
incorrect.
Example:
class A : <Cursor>B
{
}
Currently we get 'NotImplemented:{TypedText public}{Colon :} (40)'
but the correct line is just 'NotImplemented:{TypedText public} (40)'
The fix introduces more specific scope that occurs between ':' and '{'
It allows us to determine when we don't need to add ':' as a second
chunk to the public/protected/private access modifiers.

[DeLICM] Do not try to map to multiple array elements.
Add check and skip when the store used to determine the target accesses
multiple array elements. Only a single array location should for
mapping the scalar. Having multiple creates problems when deciding which
element to load from. While MemoryAccess::getAddressFunction() should
select just one of them, other problems arise in code that assumes
that there is just one target element per statement instance.
This fixes llvm.org/PR34989
This also reverts r313902 which fixed llvm.org/PR34485 also caused by
a non-functional target array element. This patch avoids the situation
to occur in the first place.

X86CallFrameOptimization: Recognize 'store 0/-1 using and/or' idioms
Summary:
r264440 added or/and patterns for storing -1 or 0 with the intention of decreasing code size. However,
X86CallFrameOptimization does not recognize these memory accesses so it will not replace them with push's when profitable.
This patch fixes this problem by teaching X86CallFrameOptimization these store 0/-1 idioms.
An alternative fix would be to prevent the 'store 0/1 idioms' patterns from firing when accessing the stack. This would save
the need to teach the pass about these idioms. However, because X86CallFrameOptimization does not always fire we may result
in cases where neither X86CallFrameOptimization not the patterns for 'store 0/1 idioms' fire.

[ConstantFolding] Avoid assert when folding ptrtoint of vectorized GEP
Summary:
Got asserts in llvm::CastInst::getCastOpcode saying:
`DestBits == SrcBits && "Illegal cast to vector (wrong type or size)"' failed.
Problem seemed to be that llvm::ConstantFoldCastInstruction did
not handle ptrtoint cast of a getelementptr returning a vector
correctly. I assume such situations are quite rare, since the
GEP needs to be considered as a constant value (base pointer
being null).
The solution used here is to simply avoid the constant fold
of ptrtoint when the value is a vector. It is not supported,
and by bailing out we do not fail on assertions later on.

[LangRef] Update description of Constant Expressions
Summary:
When describing trunc/zext/sext/ptrtoint/inttoptr in the chapter
about Constant Expressions we now simply refer to the Instruction
Reference. As far as I know there are no difference when it comes
to the semantics and the argument constraints. The only difference
is that the syntax is slighly different for the constant expressions,
regarding the use of parenthesis in constant expressions.
Referring to the Instruction Reference is the same solution as
already used for several other operations, such as bitcast.
The main goal was to add information that vector types are allowed
also in trunc/zext/sext/ptrtoint/inttoptr constant expressions.
That was not explicitly mentioned earlier, and resulted in some
questions in the review of https://reviews.llvm.org/D38546
