[ARM] Look through concat when lowering in-place shuffles (VZIP, ..)
Currently, we canonicalize shuffles that produce a result larger than
their operands with:
shuffle(concat(v1, undef), concat(v2, undef))
->
shuffle(concat(v1, v2), undef)
because we can access quad vectors (see PerformVECTOR_SHUFFLECombine).
This is useful in the general case, but there are special cases where
native shuffles produce larger results: the two-result ops.
We can look through the concat when lowering them:
shuffle(concat(v1, v2), undef)
->
concat(VZIP(v1, v2):0, :1)

dozens of VMOVs.

MIR Serialization: initialize the fields without the default initializers in yaml::MachineFunction
My commit r239790 which introduced serialization for simple machine function attributes didn't
initialize them when parsing because I have misread the documentation for YAML IO's mapOptional
method. The mapOptional method doesn't actually set the values to the values returned by the
default constructor for that type when the key value pair is missing, it just doesn't modify
those values, so they still contain the value that was set during initialization by the default
constructor. But the fields in yaml::MachineFunction with types like unsigned and bool are not
initialized by default, and thus they can still be uninitialized after mapOptional during parsing.

They had been getting emitted as a section + offset reference, which
is bogus since the value needs to be the offset within the GOT, not

[X86] Cache variables that only depend on the subtarget
There is a one-to-one relationship between X86Subtarget and
X86FrameLowering, but every frame lowering method would previously pull
the subtarget off the MachineFunction and query some subtarget
properties.
Over time, these locals began to grow in complexity and it became
important to keep their names and meaning in sync across all of the
frame lowering methods, leading to duplication. We can eliminate that
duplication by computing them once in the constructor.

Move the personality function from LandingPadInst to Function
The personality routine currently lives in the LandingPadInst.
This isn't desirable because:
- All LandingPadInsts in the same function must have the same
personality routine. This means that each LandingPadInst beyond the
first has an operand which produces no additional information.
- There is ongoing work to introduce EH IR constructs other than
LandingPadInst. Moving the personality routine off of any one
particular Instruction and onto the parent function seems a lot better
than have N different places a personality function can sneak onto an
exceptional function.

However, relative labels (which are temporary symbols) are apparently not stored
in the Symbols StringMap, so we end up creating a new {$,.L}tmp symbol
({$,.L}tmp00, {$,.L}tmp10 etc.) each time we create an MCSymbolRefExpr by
passing in the symbol name as a StringRef.
Fortunately, there is a version of MCSymbolRefExpr::create() which takes an
MCSymbol* and we already have an MCSymbol* at that point, so we can just pass
that in instead of the StringRef.
I also removed the local StringRef calls to MCSymbolRefExpr::create() from
expandMemInst(), as those cases can be handled by evaluateRelocExpr() anyway.

[PM/AA] Suffix lots of member variables that directly use enumeration
names for counts with the word 'Count' to make them less ambiguous.
This will be an actual error if we use unscoped enums for any of these,
and generally this seems much clearer to read.
Also, use clang-format to normalize the formatting of this code which
seems to have been needlessly odd.
No functionality changed here.

[PM/AA] Remove the UnknownSize static member from AliasAnalysis.
This is now living in MemoryLocation, which is what it pertains to. It
is also an enum there rather than a static data member which is left
never defined.

[PM/AA] Remove the Location typedef from the AliasAnalysis class now
that it is its own entity in the form of MemoryLocation, and update all
the callers.
This is an entirely mechanical change. References to "Location" within
AA subclases become "MemoryLocation", and elsewhere
"AliasAnalysis::Location" becomes "MemoryLocation". Hope that helps
out-of-tree folks update.
