start by reading only a mach header sized chunk of memory, then
check it for a valid mach-o magic # and use the size of the load

[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.

[TableGen][AsmMatcherEmitter] Allow tied operands of different classes in aliases.
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.

[analyzer] Checker for uninitialized C++ objects
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.

[X86] Create X86InstrFMA3Group objects fully in a static table instead of on the heap. NFCI
Previously we heap allocated the X86InstrFMA3Group objects which were created by passing them small register/memory opcode arrays that existed as individual static tables.
Rather than a bunch of small static arrays we now have one large static table of X86InstrFMA3Group objects. Rather than storing a pointer to the opcode arrays in the X86InstrFMA3Group object, we now store have a register and memory array as part of the object. If a group doesn't have memory or register opcodes, the array entries will be 0.
This greatly simplifies the destruction of the X86InstrFMA3Info object. We no longer need to delete the X86InstrFMA3Group objects as we destruct the DenseMap. And we don't need to keep track of which ones we already deleted.
This reduces the llc binary size on my local machine by ~50k. I can only assume that's really due to the fact that we had something like 512 small static arrays that we passed to the init functions either one at a time or in pairs. So there were between 256 and 512 distinct calls to the init functions in the initOnceImpl method.

[X86] Move the 'vmovq.s' and similar assembly strings for EVEX vector moves with reversed operands to InstAliases.
The .s assembly strings allow the reversed forms to be targeted from assembly which matches gas behavior. But when printing the instructions we should print them without the .s to match other tooling like objdump. By using InstAliases we can use the normal string in the instruction and just hide it from the assembly parser.

[TableGen] Prevent double flattening of InstAlias asm strings in the asm matcher emitter.
Unlike CodeGenInstruction, CodeGenInstAlias was flatting asm strings in its constructor. For instructions it was the users responsibility to flatten the string.
AsmMatcherEmitter didn't know this and treated them the same. This caused double flattening of InstAliases. This is mostly harmless unless the desired assembly string contains curly braces. The second flattening wouldn't know to ignore these and would remove the curly braces. And for variant 1 it would remove the contents of them as well.
To mitigate this, this patch makes removes the flattening from the CodeGenIntAlias constructor and modifies AsmWriterEmitter to account for the flattening not having been done.
