Instead trying to pro-actively determine if the first line in a
crashlog contains meta data, change the heuristic to do the following:
1. To trying to parse the whole file. If that fails, then:
2. Strip the first line and try parsing the remainder of the file. If
that fails, then:
3. Fall back to the textual crashlog parser.

This fixes warnings about implicitly declared `_umul128` and
`__shiftright128` when building for x86_64 with clang-cl.
Use `_MSC_VER` instead of `_LIBCPP_COMPILER_MSVC` for enabling MSVC
specific code; `_MSC_VER` is defined both in clang-cl and MSVC,
while `_LIBCPP_COMPILER_MSVC` only is defined if building with the
actual MSVC compiler.
Include `ryu.h` at the head of `d2s_intrinsics.h`, as it uses
the `_LIBCPP_64_BIT` define, which is defined in `ryu.h`.
Now the Ryu files build without warnings with clang-cl for i386,
x86_64, arm and aarch64.

Fix compiler warnings.
Fixup many of the tests to have non-empty parallel regions as they are

Due to a typo of 256 to 226, the SIInsertWaitcnt pass thinks

This introduces a new "ptrauth" operand bundle to be used in
call/invoke. At the IR level, it's semantically equivalent to an
@llvm.ptrauth.auth followed by an indirect call, but it additionally
provides additional hardening, by preventing the intermediate raw
pointer from being exposed.
This mostly adds the IR definition, verifier checks, and support in
a couple of general helper functions. Clang IRGen and backend support
will come separately.
Note that we'll eventually want to support this bundle in indirectbr as
well, for similar reasons. indirectbr currently doesn't support bundles
at all, and the IR data structures need to be updated to allow that.

ObjectFileMachO, for a couple of special binaries at the initial
launch, needs to find segment load addresses before the Target's
SectionLoadList has been initialized. The calculation to find
the first segment, which is at the same address as the mach header,
was not correct if the binary was in the Darwin shared cache.
Update the logic to handle that case.

Post-commit review feedback suggested dropping the deprecated
diagnostic for the 'noreturn' macro (the diagnostic from the header
file suffices and the macro diagnostic could be confusing) and to only
issue the deprecated diagnostic for [[_Noreturn]] when the attribute
identifier is either directly written or not from a system macro.
Amends the commit made in 5029dce492.
This reverts commit 0f73fb18ca.
Use llvm/Profile/MIBEntryDef.inc instead of relative path.
Generated the raw profile data with `-mllvm
-enable-name-compression=false` so that builbots where the reader is
built without zlib do not fail.
Also updated the test build instructions.
While one cannot of course statically initialize an allocatable component
of an instance of a derived type, its mere presence should not prevent
DATA initialization of the other nonallocatable components. Semantics
was treating the existence of an allocatable component as a case of
"default initialization", which it is, but not one that should run
afoul of C877. Add another Boolean argument to IsInitialized() to allow
for a more nuanced test.

Add support for getenv as defined by the Open Group's "System Interface &
Header" in https://pubs.opengroup.org/onlinepubs/7908799/xsh/getenv.html
getenv requires a standard way of accessing the environment,
so a pointer to the environment is added to the startup in crt1.
Consquently, this function is not usable on top of other libcs.
Added starts_with method to StringView. getenv function uses it.

This patch adds support for optional memory profile information to be
included with and indexed profile. The indexed profile header adds a new
field which points to the offset of the memory profile section (if
present) in the indexed profile. For users who do not utilize this
feature the only overhead is a 64-bit offset in the header.
The memory profile section contains (1) profile metadata describing the
information recorded for each entry (2) an on-disk hashtable containing
the profile records indexed via llvm::md5(function_name). We chose to
introduce a separate hash table instead of the existing one since the
indexing for the instrumented fdo hash table is based on a CFG hash
which itself is perturbed by memprof instrumentation.

While the contents of the profile are backwards compatible the header
itself is not. For example, when adding new fields to the header results

* While annoying, this is the only way to get C++ exception handling out of the happy path for normal iteration.
* Implements sq_length and sq_item for the sequence protocol (used for iteration, including list() construction).
* Implements mp_subscript for general use (i.e. foo[1] and foo[1:1]).
* For constructing a `list(op.results)`, this reduces the time from ~4-5us to ~1.5us on my machine (give or take measurement overhead) and eliminates C++ exceptions, which is a worthy goal in itself.
* Compared to a baseline of similar construction of a three-integer list, which takes 450ns (might just be measuring function call overhead).
