The initial implementaiton was using the C++ typeof keyword. This
causes the compiler to spew warnings unnecissarilly. This patch removes
the uses of typeof and replaces them with explicit typedefs of the
function types.

The variants added by this patch are:
- SQINC signed increment, e.g. sqinc x0, w0, all, mul #4
- SQDEC signed decrement, e.g. sqdec x0, w0, all, mul #4
- UQINC unsigned increment, e.g. uqinc w0, all, mul #4
- UQDEC unsigned decrement, e.g. uqdec w0, all, mul #4
This patch includes asmparser changes to parse a GPR64 as a GPR32 in
order to satisfy the constraint check:
x0 == GPR64(w0)
in:
sqinc x0, w0, all, mul #4

2 of these tests were clearly not doing what the comments
said they were doing.
The last test was added at rL177933 with no assertions
(presumably it used to crash). But either we don't have
that problem anymore, or this test is folded sooner,
so we don't hit the bug that was fixed by disabling late
FP constant creation. Looking at this as part of reviewing
D48289.

Summary:
Following up on and complementing D44404 and other sanitizer allocators.
Currently many allocator specific errors (OOM, for example) are reported as
a text message and CHECK(0) termination, no stack, no details, not too
helpful nor informative. To improve the situation, detailed and structured
common errors were defined and reported under the appropriate conditions.
Common tests were generalized a bit to cover a slightly different TSan
stack reporting format, extended to verify errno value and returned
pointer value check is now explicit to facilitate debugging.

The test makes %t.fake a symlink to %t.real by running `ln -sf %t.real
%t.fake`. If %t.fake already is a symlink to %t.real when this runs (e.g. if
the test has run before), then this effectively becomes `ln -sf %t.real %t.real`,
symlinking the directory to itself. At least on my mac, this leads to the
directory containing itself.
As fix, just remove %t.fake before creating the symlink. To clean up build dirs
on bots, also remove %t.real for a while.

Summary:
In this patch I aim to do the following:
1) Create an lldb-framework target that acts as the target that handles generating LLDB.framework. Previously, liblldb acted as the target for generating the framework in addition to generating the actual lldb library. This made the target feel overloaded.
2) Centralize framework generation as much as it makes sense to do so.
3) Create a target lldb-suite, which depends on every tool and library that makes liblldb fully functional. One result of having this target is it makes tracking dependencies much clearer.

materializing weak symbols as strong.
This removes some elaborate flag tweaking and plays nicer with RuntimeDyld,
which relies of weak/common flags to determine whether it should emit a given
weak definition. (Switching to strong up-front makes it appear as if there is
already an overriding definition, which would require an extra back-channel to
override).

Summary:
This has multiple advantages:
- we need only one function argument/instance variable instead of three
- no need to default initialize variables
- no custom parsing code
- VersionTuple has comparison operators, which makes version comparisons much

When the destination register of a XOP instruction is an XMM register, bits
[255:128] of the corresponding YMM register are cleared.
When the destination register of a EVEX encoded instruction is an XMM/YMM
register, the upper bits of the corresponding ZMM are cleared.
On processors that feature AVX512, a write to an XMM registers always clears the
upper portion of the corresponding ZMM register if the instruction is VEX or
EVEX encoded.
These new tests show some interesting cases which aren't correctly analyzed by
llvm-mca. The lack of knowledge related to the implicit update on the
super-registers is addressed by D48225.

Allow a tied operand of a different operand class in InstAliases,
so that the operand can be printed (and added to the MC instruction)
as the appropriate register. For example, 'GPR64as32', which would
be printed/parsed as a 32bit register and should match a tied 64bit
register operand, where the former is a sub-register of the latter.
This patch also generalizes the constraint checking to an overrideable
method in MCTargetAsmParser, so that target asmparsers can specify
whether a given operand satisfies the tied register constraint.

This checker analyzes C++ constructor calls, and reports uninitialized fields.
Due to the nature of this problem (uninitialized fields after an object
construction), this checker doesn't search for bugs, but rather is a tool to
enforce a specific programming model where every field needs to be initialized.
This checker lands in alpha for now, and a number of followup patches will be
made to reduce false negatives and to make it easier for the user to understand
what rules the checker relies on, eg. whether a derived class' constructor is
responsible for initializing inherited data members or whether it should be
handled in the base class' constructor.

This patch adds instructions for comparing elements from two vectors, e.g.
cmpgt p0.s, p0/z, z0.s, z1.s
and also adds support for comparing to a 64-bit wide element vector, e.g.
cmpgt p0.s, p0/z, z0.s, z1.d
The patch also contains aliases for certain comparisons, e.g.:
cmple p0.s, p0/z, z0.s, z1.s => cmpge p0.s, p0/z, z1.s, z0.s
cmplo p0.s, p0/z, z0.s, z1.s => cmphi p0.s, p0/z, z1.s, z0.s
cmpls p0.s, p0/z, z0.s, z1.s => cmphs p0.s, p0/z, z1.s, z0.s
cmplt p0.s, p0/z, z0.s, z1.s => cmpgt p0.s, p0/z, z1.s, z0.s

This allows matchers like:
friendDecl(hasType(cxxRecordDecl(...)))
friendDecl(hasType(asString(...)))
It seems that hasType is probably the most reasonable narrowing matcher to
overload, since it is already used to narrow to other declaration kinds.
