Summary:
Instead of hardcoding ClangASTContext and ObjCLanguageRuntime, we can
generalize this by creating the method GetRuntimeType in
LanguageRuntime and moving the current MaybeCalculateCompleteType
implementation into ObjCLanguageruntime::GetRuntimeType

<a> tags are added for the parents and members of records and return type and
params of functions. The link redirects to the reference's info file.
The directory path where each info file will be saved is now generated in the
serialization phase and stored as an attribute in each Info.
Bitcode writer and reader were modified to handle the new attributes.

All callers had a PDBFile object at hand, so call
Pdb.createIndexedStream() instead, which pre-populates all the arguments
(and returns nullptr for kInvalidStreamIndex).
Also change safelyCreateIndexedStream() to only take the string index,
and update callers. Make the method public and call it in two places
that manually did the bounds checking before.
No intended behavior change.

This paves the way for using passive segments in pthread builds, which

This patch series adds support for the next-generation arch13
CPU architecture to the SystemZ backend.
This includes:
- Basic support for the new processor and its features.
- Support for low-level builtins mapped to new LLVM intrinsics.
- New high-level intrinsics in vecintrin.h.
- Indicate support by defining __VEC__ == 10303.
Note: No currently available Z system supports the arch13
architecture. Once new systems become available, the
official system name will be added as supported -march name.

We can use the C flag from NEG to detect that the input was zero.
Really we could probably use the Z flag too. But C matches what
we'd do for usubo 0, X.
Haven't found a test case for this due to the usubo formation
in CGP. But I verified if I comment out the CGP code this
transformation catches some of the same cases.

Continue in the spirit of D63618, and use exit count reasoning to prove away loop exits which can not be taken since the backedge taken count of the loop as a whole is provably less than the minimal BE count required to take this particular loop exit.
As demonstrated in the newly added tests, this triggers in a number of cases where IndVars was previously unable to discharge obviously redundant exit tests. And some not so obvious ones.

The "line" attribute is now the physical line within the source file for the location. A "presumedLine" attribute is printed when the presumed line number does not match the given source line number. We continue to not print repeated line information in subsequent source locations, but we track presumed and actual lines separately.

Support SIGINFO (and SIGUSR1 for POSIX purposes) to tell what
long-running jobs are doing, as inspired by BSD tools (including on
macOS), by dumping the current PrettyStackTrace.
This adds a new kind of signal handler for non-fatal "info" signals,
similar to the "interrupt" handler that already exists for SIGINT
(Ctrl-C). It then uses that handler to update a "generation count"
managed by the PrettyStackTrace infrastructure, which is then checked
whenever a PrettyStackTraceEntry is pushed or popped on each
thread. If the generation has changed---i.e. if the user has pressed
Ctrl-T---the stack trace is dumped, though unfortunately it can't
include the deepest entry because that one is currently being
constructed/destructed.

Summary:
r363675 changed the exec modification helper function, now called
execMayBeModifiedBeforeUse, so that if no UseMI is specified it checks
all instructions in the basic block, even beyond the last use. That
meant that the DPP combiner no longer worked in any basic block that
ended with a control flow instruction, and in particular it didn't work
on code sequences generated by the atomic optimizer.
Fix it by reinstating the old behaviour but in a new helper function
execMayBeModifiedBeforeAnyUse, and limiting the number of instructions
scanned.

Summary:
We currently have man large arrays containing initializers for our command options.
These tables are tricky maintain as we don't have any good place to check them for consistency and
it's also hard to read (`nullptr, {}, 0` is not very descriptive).
This patch fixes this by letting table gen generate those tables. This way we can have a more readable
syntax for this (especially for all the default arguments) and we can let TableCheck check them
for consistency (e.g. an option with an optional argument can't have `eArgTypeNone`, naming of flags', etc.).
Also refactoring the related data structures can now be done without changing the hundred of option initializers.
For example, this line:
```
{LLDB_OPT_SET_ALL, false, "hide-aliases", 'a', OptionParser::eNoArgument, nullptr, {}, 0, eArgTypeNone, "Hide aliases in the command list."},
```
becomes this:
```
def hide_aliases : Option<"hide-aliases", "a">, Desc<"Hide aliases in the command list.">;
```
For now I just moved a few initializers to the new format to demonstrate the change. I'll slowly migrate the other
option initializers tables in separate patches.
