This refactoring adds a few "event" functions (start/end loop-seq/loop) for
readability of the core function of codegen. This also prepares sparse tensor
output codegen, where these "event" functions will provide convenient
placeholders to start or stop insertion bookkeeping.
This revision also includes a few various minor changes that kept on
pending in my local workspace.

This diff does away with `addEntriesForFunctionsWithoutUnwindInfo()`,
because `addSymbol()` can now determine which functions need those
entries.
While overhauling UnwindInfoSection, I also parallelized the relocation
of the contents of the CUEs. This somewhat offsets the time regression
from creating one InputSection per CUE (which was done in D109944).

Compact unwind entries (CUEs) contain pointers to their respective
function symbols. However, during the link process, it's far more useful
to have pointers from the function symbol to the CUE than vice versa.
This diff adds that pointer in the form of `Defined::compactUnwind`.
In particular, when doing dead-stripping, we want to mark CUEs live when
their function symbol is live; and when doing ICF, we want to dedup
sections iff the symbols in that section have identical CUEs. In both
cases, we want to be able to locate the symbols within a given section,
as well as locate the CUEs belonging to those symbols. So this diff also
adds `InputSection::symbols`.
The ultimate goal of this refactor is to have ICF support dedup'ing
functions with unwind info, but that will be handled in subsequent
diffs. This diff focuses on simplifying `-dead_strip` --
`findFunctionsWithUnwindInfo` is no longer necessary, and
`Defined::isLive()` is now a lot simpler. Moreover, UnwindInfoSection no
longer has to check for dead CUEs -- we simply avoid adding them in the
first place.
Additionally, we now support stripping of dead LSDAs, which follows
quite naturally since `markLive()` can now reach them via the CUEs.

This is a test-only failure. The test wrongly assumes that this gets us
a tagged pointer:
```
NSObject* num1 = @7;
assert(isTaggedPtr(num1));
```
However, on newer deployment targets that have “const data support” we
get a “normal” pointer to constant object.

Polynomial approximation can be extented to support N-d vectors.
N-dimensional vectors are useful when vectorizing operations on N-dimensional

Mark LWG2731 as complete. The type alias `mutex_type` is only provided if
`scoped_lock` is given one mutex type and it has been implemented that
way since the beginning of Clang 5 it seems. There already are tests for
verifying existence (and lack thereof) for `mutex_type` type alias
depending on the number of mutex types, so there is nothing to
do for this LWG issue.

like preciate of an attribute, we may embed certain placeholder in the C

be the base type like mlir::Type, it's better not to use the derived
type which is based on the implementation.

This patch refactors the shared_ptr methods from being defined out-of-line
to being defined inline in the class, like what we do for all new code in
the library. The benefits of doing that are that code is not as scattered
around and is hence easier to understand, and it avoids a ton of duplication
due to SFINAE checks. Defining the method where it is declared also removes
the possibility for mismatched attributes.
As a fly-by change, this also:
- Adds a few _LIBCPP_HIDE_FROM_ABI attributes
- Uses __enable_if_t instead of enable_if as a function argument, to match
the style that we use everywhere else.

We make assumption that:
getDeclForComment(getDeclForComment(X)) == getDeclForComment(X)
but this is not true if you have a template
instantionation of a template instantiation, which is the case when, for
example, you have a <=> operator in a templated class.
This fix makes getDeclForComment() call itself recursively to ensure
this property is always true.

It was discovered that an extra register COPY remained when expanding a

A simple fix for this is to COPY the address registers before the loop and
use that new vreg instead.
