[AArch64][GlobalISel] Choose CCAssignFns per-argument for tail call lowering
When checking for tail call eligibility, we should use the correct CCAssignFn
for each argument, rather than just checking if the caller/callee is varargs or
not.
This is important for tail call lowering with varargs. If we don't check it,
then basically any varargs callee with parameters cannot be tail called on
Darwin, for one thing. If the parameters are all guaranteed to be in registers,
this should be entirely safe.
On top of that, not checking for this could potentially make it so that we have
the wrong stack offsets when checking for tail call eligibility.
Also refactor some of the stuff for CCAssignFnForCall and pull it out into a
helper function.
Update call-translator-tail-call.ll to show that we can now correctly tail call
on Darwin. Also add two extra tail call checks. The first verifies that we still
respect the caller's stack size, and the second verifies that we still don't
tail call when a varargs function has a memory argument.

[CodeGen] Replace -max-jump-table-size with -max-jump-table-targets
Modern processors predict the targets of an indirect branch regardless of
the size of any jump table used to glean its target address. Moreover,
branch predictors typically use resources limited by the number of actual
targets that occur at run time.
This patch changes the semantics of the option `-max-jump-table-size` to limit
the number of different targets instead of the number of entries in a jump
table. Thus, it is now renamed to `-max-jump-table-targets`.
Before, when `-max-jump-table-size` was specified, it could happen that
cluster jump tables could have targets used repeatedly, but each one was
counted and typically resulted in tables with the same number of entries.
With this patch, when specifying `-max-jump-table-targets`, tables may have
different lengths, since the number of unique targets is counted towards the
limit, but the number of unique targets in tables is the same, but for the
last one containing the balance of targets.

seem to fail with this mode enabled, we also can't just enable it globally for now.
As we touch the surrounding code all the time and also want to refactor parts of it, we
should be a bit more ambitious with our testing efforts.
So this patch adds two basic tests that enable this mode and do some
basic expression parsing which should hopefully be basic enough to not
break anywhere but still lets us know if this mode works at all (i.e. setting up the
ExternalASTMerger in LLDB, using its basic import functionality to move declarations

Have ABI plugins vend llvm MCRegisterInfo data
Summary:
I was recently surprised to learn that there is a total of 2 (two) users
of the register info definitions contained in the ABI plugins. Yet, the
defitions themselves span nearly 10kLOC.
The two users are:
- dwarf expression pretty printer
- the mechanism for augmenting the register info definitions obtained
over gdb-remote protocol (AugmentRegisterInfoViaABI)
Both of these uses need the DWARF an EH register numbers, which is
information that is already available in LLVM. This patch makes it
possible to do so.
It adds a GetMCRegisterInfo method to the ABI class, which every class
is expected to implement. Normally, it should be sufficient to obtain
the definitions from the appropriate llvm::Target object (for which I
provide a utility function), but the subclasses are free to construct it
in any way they deem fit.
We should be able to always get the MCRegisterInfo object from llvm,
with one important exception: if the relevant llvm target was disabled
at compile time. To handle this, I add a mechanism to disable the
compilation of ABI plugins based on the value of LLVM_TARGETS_TO_BUILD
cmake setting. This ensures all our existing are able to create their
MCRegisterInfo objects.
The new MCRegisterInfo api is not used yet, but the intention is to make
use of it in follow-up patches.

[ELF] Add -z separate-loadable-segments to complement separate-code and noseparate-code
D64906 allows PT_LOAD to have overlapping p_offset ranges. In the
default R RX RW RW layout + -z noseparate-code case, we do not tail pad
segments when transiting to another segment. This can save at most
3*maxPageSize bytes.
a) Before D64906, we tail pad R, RX and the first RW.
b) With -z separate-code, we tail pad R and RX, but not the first RW (RELRO).
In some cases, b) saves one file page. In some cases, b) wastes one
virtual memory page. The waste is a concern on Fuchsia. Because it uses
compressed binaries, it doesn't benefit from the saved file page.
This patch adds -z separate-loadable-segments to restore the behavior before
D64906. It can affect section addresses and can thus be used as a
debugging mechanism (see PR43214 and ld.so partition bug in
