This is to support both the cases where the base address is relocated

address is a constant (typically zero) and relocations are on the
offsets themselves.

[lldb] Move register info "augmentation" from gdb-remote into ABI
Summary:
Previously the ABI plugin exposed some "register infos" and the
gdb-remote code used those to fill in the missing bits. Now, the
"filling in" code is in the ABI plugin itself, and the gdb-remote code
just invokes that.
The motivation for this is two-fold:
a) the "augmentation" logic is useful outside of process gdb-remote. For
instance, it would allow us to avoid repeating the register number
definitions in minidump code.
b) It gives more implementation freedom to the ABI classes. Now that
these "register infos" are essentially implementation details, classes
can use other methods to obtain dwarf/eh_frame register numbers -- for
instance they can consult llvm MC layer.
Since the augmentation code was not currently tested anywhere, I took
the opportunity to create a simple test for it.

[asan] Remove debug locations from alloca prologue instrumentation
Summary:
This fixes https://llvm.org/PR26673
"Wrong debugging information with -fsanitize=address"
where asan instrumentation causes the prologue end to be computed
incorrectly: findPrologueEndLoc, looks for the first instruction
with a debug location to determine the prologue end. Since the asan
instrumentation instructions had debug locations, that prologue end was
at some instruction, where the stack frame is still being set up.
There seems to be no good reason for extra debug locations for the
asan instrumentations that set up the frame; they don't have a natural
source location. In the debugger they are simply located at the start
of the function.
For certain other instrumentations like -fsanitize-coverage=trace-pc-guard
the same problem persists - that might be more work to fix, since it
looks like they rely on locations of the tracee functions.
This partly reverts
aaf4bb239487e0a3b20a8eaf94fc641235ba2c29
"[asan] Set debug location in ASan function prologue"
whose motivation was to give debug location info to the coverage callback.
Its test only ensures that the call to @__sanitizer_cov_trace_pc_guard is
given the correct source location; as the debug location is still set in
ModuleSanitizerCoverage::InjectCoverageAtBlock, the test does not break.
So -fsanitize-coverage is hopefully unaffected - I don't think it should
rely on the debug locations of asan-generated allocas.

[LiveDebugValues] Introduce entry values of unmodified params
The idea is to remove front-end analysis for the parameter's value
modification and leave it to the value tracking system. Front-end in some
cases marks a parameter as modified even the line of code that modifies the
parameter gets optimized, that implies that this will cover more entry
values even. In addition, extending the support for modified parameters
will be easier with this approach.
Since the goal is to recognize if a parameter’s value has changed, the idea
at very high level is: If we encounter a DBG_VALUE other than the entry
value one describing the same variable (parameter), we can assume that the
variable’s value has changed and we should not track its entry value any
more. That would be ideal scenario, but due to various LLVM optimizations,
a variable’s value could be just moved around from one register to another
(and there will be additional DBG_VALUEs describing the same variable), so
we have to recognize such situation (otherwise, we will lose a lot of entry
values) and salvage the debug entry value.

[LLDB] Set the right address size on output DataExtractors from ObjectFile
If filling in a DataExtractor from an ObjectFile, e.g. via the

ObjectFile's m_data member is initialized without knowledge about
the address size (so the address size is set based on the host's

virtual methods implemented in subclasses (like GetAddressByteSize())

The current range extension thunk framework does not handle a relocation

used by jumps/calls to local functions on some RELA targets (AArch64,
powerpc ELFv1, powerpc64 ELFv2, etc). See PR40438 and the following
code for examples:
// clang -target $target a.cc
// .text.cold may be placed in a separate output section.
// The distance between bar in .text.cold and foo in .text may be larger than 128MiB.
static void foo() {}
__attribute__((section(".text.cold"))) static int bar() { foo(); return
0; }
__attribute__((used)) static int dummy = bar();
This patch makes such thunks with addends work for AArch64. The target
independent part can be reused by PPC in the future.
On REL targets (ARM, MIPS), jumps/calls are not represented as
STT_SECTION + non-zero addend (see

[ARM,MVE] Add intrinsics to deal with predicates.
Summary:
This commit adds the `vpselq` intrinsics which take an MVE predicate
word and select lanes from two vectors; the `vctp` intrinsics which
create a tail predicate word suitable for processing the first m
elements of a vector (e.g. in the last iteration of a loop); and
`vpnot`, which simply complements a predicate word and is just
syntactic sugar for the `~` operator.
The `vctp` ACLE intrinsics are lowered to the IR intrinsics we've
already added (and which D70592 just reorganized). I've filled in the
missing isel rule for VCTP64, and added another set of rules to
generate the predicated forms.
I needed one small tweak in MveEmitter to allow the `unpromoted` type
modifier to apply to predicates as well as integers, so that `vpnot`
doesn't pointlessly convert its input integer to an `<n x i1>` before
complementing it.

[ARM,MVE] Rename and clean up VCTP IR intrinsics.
Summary:
D65884 added a set of Arm IR intrinsics for the MVE VCTP instruction,
to use in tail predication. But the 64-bit one doesn't work properly:
its predicate type is `<2 x i1>` / `v2i1`, which isn't a legal MVE
type (due to not having a full set of instructions that manipulate it
usefully). The test of `vctp64` in `basic-tail-pred.ll` goes through
`opt` fine, as the test expects, but if you then feed it to `llc` it
causes a type legality failure at isel time.
The usual workaround we've been using in the rest of the MVE
intrinsics family is to bodge `v2i1` into `v4i1`. So I've adjusted the
`vctp64` IR intrinsic to do that, and completely removed the code (and
test) that uses that intrinsic for 64-bit tail predication. That will
allow me to add isel rules (upcoming in D70485) that actually generate
the VCTP64 instruction.
Also renamed all four of these IR intrinsics so that they have `mve`
in the name, since its absence was confusing.

[ARM,MVE] Add an InstCombine rule permitting VPNOT.
Summary:
If a user writing C code using the ACLE MVE intrinsics generates a
predicate and then complements it, then the resulting IR will use the
`pred_v2i` IR intrinsic to turn some `<n x i1>` vector into a 16-bit
integer; complement that integer; and convert back. This will generate
machine code that moves the predicate out of the `P0` register,
complements it in an integer GPR, and moves it back in again.
This InstCombine rule replaces `i2v(~v2i(x))` with a direct complement
of the original predicate vector, which we can already instruction-
select as the VPNOT instruction which complements P0 in place.

As i have briefly discusses in IRC with Tim, the original motivation
can no longer be recovered, too much time has passed.
However i believe that the original fold was doing the right thing,
we should be performing such a transformation even if the inner `add`
will not go away - that will still unchain the comparison from `add`,
it will no longer need to wait for `add` to compute.
Doing so doesn't seem to break any particular idioms,

[update_cc_test_checks.py] Handle extern "C" and namespaces
Summary:
My change to use the clang AST JSON dump did not handle functions declared
inside scopes other than the root TranslationUnitDecl. After this change
update_cc_test_checks.py also works for C++ test cases that use extern "C"
and namespaces.

[UpdateTestChecks] Share the code to parse RUN: lines between all scripts
Summary:
This commit also introduces a common.debug() function to avoid many
`if args.verbose:` statements. Depends on D70428.
