This patch introduces a VPInstructionToVPRecipe transformation, which
allows us to generate code for a VPInstruction based VPlan re-using the
existing infrastructure.

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.

CompileOnDemandLayer2 is a replacement for CompileOnDemandLayer built on the ORC
Core APIs. Functions in added modules are extracted and compiled lazily.
CompileOnDemandLayer2 supports multithreaded JIT'd code, and compilation on
multiple threads.

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).

Ideally we'd reuse the shuffle mask pattern matching in TargetTransformInfo::getInstructionThroughput here to easily add support for all TargetTransformInfo::ShuffleKind without mass code duplication, I've added a TODO for now but D48236 should help us here.

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
  simpler

[llvm-mca] Add tests for XOP and AVX512 instructions that implicitly clear the upper portion of a super-register.

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.
