Add a new DynamicLoader plugin that uses SPI that are in development

about loaded images, instead of reading dyld internal data structures.
These new SPI don't exist on older releases, and new packets are
needed from debugserver to use them (those changes are already committed).
I had to change the minimum deployment target for debugserver in the xcode
project file to macOS 10.10 so that debugserver will use the
[[NSProcessInfo processInfo] operatingSystemVersion]
call in MachProcess::GetOSVersionNumbers to get the operarting system
version # -- this API is only available in macOS 10.10 and newer
("OS X Yosemite", released Oct 2014). If we have many people building
llvm.org lldb on older systems still, we can back off on this for the
llvm.org sources.
There should be no change in behavior with this commit, either to
older darwin systems or newer darwin systems.
For now the new DynamicLoader plugin is never activated - I'm forcing
the old plugin to be used in DynamicLoaderDarwin::UseDYLDSPI.
I'll remove that unconditional use of the old plugin soon, so the
newer plugin is used on the newest Darwin platforms.

Summary:
This is a fixed-up version of D21612, to address failure identified post-commit.
Original commit description:
This patch implements the initialisation and patching routines for the XRay runtime, along with the necessary trampolines for function entry/exit handling. For now we only define the basic hooks for allowing an implementation to define a handler that gets run on function entry/exit. We expose a minimal API for controlling the behaviour of the runtime (patching, cleanup, and setting the handler to invoke when instrumenting).
Fixes include:
- Gating XRay build to only Linux x86_64 and with the right dependencies in case it is the only library being built
- Including <cstddef> to fix std::size_t issue

IPRA: Fix RegMask calculation for alias registers
This patch fixes a very subtle bug in regmask calculation. Thanks to zan
jyu Wong <zyfwong@gmail.com> for bringing this to notice.
For example if CL is only clobbered than CH should not be marked
clobbered but CX, RCX and ECX should be mark clobbered. Previously for
each modified register all of its aliases are marked clobbered by
markRegClobbred() in RegUsageInfoCollector.cpp but that is wrong because
when CL is clobbered then MRI::isPhysRegModified() will return true for
CL, CX, ECX, RCX which is correct behavior but then for CX, EXC, RCX we
mark CH also clobbered as CH is aliased to CX,ECX,RCX so
markRegClobbred() is not required because isPhysRegModified already take
cares of proper aliasing register. A very simple test case has been
added to verify this change.

X86InstrInfo: No need for liveness analysis in classifyLEAReg()
classifyLEAReg() deals with switching operands from 32bit to 64bit in
order to use a LEA64_32 instruction (for three address code goodness).
It currently performs a liveness analysis to determine the kill/undef
flag for the newly added operand. This should not be necessary:
- If the previous operand had a kill flag, then the 32bit part of the
register gets killed, this will kill the super register as well.
- If the previous operand had an undef flag then we didn't care what
value we read, just use the same flag on the new operand.
(No matter what an operand with an undef flag won't affect liveness)
This makes the code independent of the presence of kill flags because it
avoids a call to MachineBasicBlock::computeRegisterLiveness().

[MSSA] Add an overload for getClobberingMemoryAccess.
A seemingly common use for the walker's getClobberingMemoryAccess
function is:
```
MemoryAccess *getClobber(MemorySSAWalker *W, MemoryUseOrDef *MUD) {
const Instruction *I = MUD->getMemoryInst();
return W->getClobberingMemoryAccess(I);
}
```
Which is kind of redundant, since walkers will ultimately query MSSA to
find out which MemoryAccess `I` maps to (...which is always `MUD`).
So, this patch adds an overload of getClobberingMemoryAccess that
accepts MemoryAccesses directly. As a result, the Instruction overload
of getClobberingMemoryAccess becomes a lightweight wrapper around our
new overload.
Additionally, this patch un`virtual`izes the Instruction overload of
getClobberingMemoryAccess, since there doesn't seem to be a walker that
benefits from that being virtual, and I can't think of how else one
would implement it. Happy to make it virtual again if we would benefit
from doing so.
