[Reproducers] Fix GDB remote flakiness during replay
This fixes the flakiness of the GDB remote reproducer during replay. It
was caused by a combination sending one ACK to many from the replay
server and the code that "flushes" any queued GDB remote packets in
GDBRemoteCommunicationClient::HandshakeWithServer.
The spurious ACK was the result of combining both implicit and explicit
handling of ACKs in the replay server. The handshake consists of an ACK
followed by an QStartNoAckMode. As long as we haven't seen any
QStartNoAckMode, we were sending implicit acknowledgments. So the first
ACK got acknowledged twice, once implicitly, and once as part of the
replay.
The reason we didn't notice this was the code in HandshakeWithServer
that "waits for any responses that might have been queued up in the
remote GDB server and flush them all". A 10ms timeout is used to move on
when no packets are left. If the second ACK didn't make it within those
10ms, all packets were offset by one.

This is a refactoring patch that removes the redundancy of performing operand reordering twice, once in buildTree() and later in vectorizeTree().
To achieve this we need to keep track of the operands within the TreeEntry struct while building the tree, and later in vectorizeTree() we are just accessing them from the TreeEntry in the right order.

I tried to just use an f64 atomic load and add isel patterns to MOVSD(which the domain fixing pass can turn to MOVQ), but the atomic_load SDNode in TargetSelectionDAG.td requires the type to be integer.
So I've emitted VZEXT_LOAD instead which should be selected by isel to a MOVQ. Hopefully we don't need a specific atomic flavor of this. I kept the memory operand from the original AtomicSDNode. I wasn't sure if I might need to set the MOVolatile flag?

IR: Support parsing numeric block ids, and emit them in textual output.
Just as as llvm IR supports explicitly specifying numeric value ids
for instructions, and emits them by default in textual output, now do
the same for blocks.
This is a slightly incompatible change in the textual IR format.
Previously, llvm would parse numeric labels as string names. E.g.
define void @f() {
br label %"55"
55:
ret void
}
defined a label *named* "55", even without needing to be quoted, while
the reference required quoting. Now, if you intend a block label which
looks like a value number to be a name, you must quote it in the
definition too (e.g. `"55":`).
Previously, llvm would print nameless blocks only as a comment, and
would omit it if there was no predecessor. This could cause confusion
for readers of the IR, just as unnamed instructions did prior to the
addition of "%5 = " syntax, back in 2008 (PR2480).
Now, it will always print a label for an unnamed block, with the
exception of the entry block. (IMO it may be better to print it for
the entry-block as well. However, that requires updating many more
tests.)
Thus, the following is supported, and is the canonical printing:
define i32 @f(i32, i32) {
%3 = add i32 %0, %1
br label %4
4:
ret i32 %3
}
New test cases covering this behavior are added, and other tests
updated as required.

We're already computing the known bits of the operands here. If the

we'll already catch this in signedAddMayOverflow(). The only other
way (and as the comment already indicates) we'll get new information

As such, we change the code to only compute known bits from assumptions,

[AliasAnalysis] Second prototype to cache BasicAA / anyAA state.
Summary:
Adding contained caching to AliasAnalysis. BasicAA is currently the only one using it.
AA changes:
- This patch is pulling the caches from BasicAAResults to AAResults, meaning the getModRefInfo call benefits from the IsCapturedCache as well when in "batch mode".
- All AAResultBase implementations add the QueryInfo member to all APIs. AAResults APIs maintain wrapper APIs such that all alias()/getModRefInfo call sites are unchanged.
- AA now provides a BatchAAResults type as a wrapper to AAResults. It keeps the AAResults instance and a QueryInfo instantiated to batch mode. It delegates all work to the AAResults instance with the batched QueryInfo. More API wrappers may be needed in BatchAAResults; only the minimum needed is currently added.
MemorySSA changes:
- All walkers are now templated on the AA used (AliasAnalysis=AAResults or BatchAAResults).
- At build time, we optimize uses; now we create a local walker (lives only as long as OptimizeUses does) using BatchAAResults.
- All Walkers have an internal AA and only use that now, never the AA in MemorySSA. The Walkers receive the AA they will use when built.
- The walker we use for queries after the build is instantiated on AliasAnalysis and is built after building MemorySSA and setting AA.
- All static methods doing walking are now templated on AliasAnalysisType if they are used both during build and after. If used only during build, the method now only takes a BatchAAResults. If used only after build, the method now takes an AliasAnalysis.

[ObjectYAML] Add basic minidump generation support
Summary:
This patch adds the ability to read a yaml form of a minidump file and
write it out as binary. Apart from the minidump header and the stream
directory, only three basic stream kinds are supported:
- Text: This kind is used for streams which contain textual data. This
is typically the contents of a /proc file on linux (e.g.
/proc/PID/maps). In this case, we just put the raw stream contents
into the yaml.
- SystemInfo: This stream contains various bits of information about the
host system in binary form. We expose the data in a structured form.
- Raw: This kind is used as a fallback when we don't have any special
knowledge about the stream. In this case, we just print the stream
contents in hex.
For this code to be really useful, more stream kinds will need to be
added (particularly for things like lists of memory regions and loaded
modules). However, these can be added incrementally.
