The LLVM-C API is relatively small so we've previously added doxygen tags
so it's easier to navigate the LLVM-C web docs. Over the years, more
headers were added without proper doxygen tags, effectively hiding them
from the main LLVM-C doxygen page. This patch adds comments to headers
which did not have them.

This patch make coroutine passes run by default in LLVM pipeline. Now
the clang and opt could handle IR inputs containing coroutine intrinsics
without special options.
It should be fine. On the one hand, the coroutine passes seems to be stable
since there are already many projects using coroutine feature.
On the other hand, the coroutine passes should do nothing for IR who doesn't
contain coroutine intrinsic.

This reverts commit 59d6e814ce0e7b40b7cc3ab136b9af2ffab9c6f8.
The cause for the revert (3 clang tests running opt -ipconstprop) was
fixed by removing those lines.
As far as I know, ipconstprop has not been used in years and ipsccp has
been used instead. This has the potential for confusion and sometimes
leads people to spend time finding & reporting bugs as well as
updating it to work with the latest API changes.
This patch moves the tests over to SCCP. There's one functional difference
I am aware of: ipconstprop propagates for each call-site individually, so
for functions that are called with different constant arguments it can sometimes
produce better results than ipsccp (at much higher compile-time cost).But
IPSCCP can be thought to do so as well for internal functions and as mentioned
earlier, the pass seems unused in practice (and there are no plans on working
towards enabling it anytime).

This patch adds bindings to C and Go for
addCoroutinePassesToExtensionPoints, which is used to add coroutine
passes to the correct locations in PassManagerBuilder.
Differential Revision: https://reviews.llvm.org/D51642
A series of patches beginning with https://reviews.llvm.org/D71898
propose to add an implementation of the coroutine passes to the new pass
manager. As part of these changes, the coroutine passes that implement
the legacy pass manager interface are renamed, to `<PassName>Legacy`.
This mirrors similar changes that have been made to many other passes in
LLVM as they've been transitioned to support both old and new pass
managers.
This commit splits out the renaming portion of that patch and commits it
in advance as an NFC (no functional change intended) commit. It renames:
* `CoroEarly` => `CoroEarlyLegacy`
* `CoroSplit` => `CoroSplitLegacy`
* `CoroElide` => `CoroElideLegacy`
* `CoroCleanup` => `CoroCleanupLegacy`
Force `-Werror=strict-prototypes` so that C API tests fail to compile if
we add a non-prototype declaration. This should help avoid regressions
like bddecba4b333f7772029b4937d2c34f9f2fda6ca was fixing.

Add a pass to lower is.constant and objectsize intrinsics
This pass lowers is.constant and objectsize intrinsics not simplified by
earlier constant folding, i.e. if the object given is not constant or if
not using the optimized pass chain. The result is recursively simplified
and constant conditionals are pruned, so that dead blocks are removed
even for -O0. This allows inline asm blocks with operand constraints to
work all the time.
The new pass replaces the existing lowering in the codegen-prepare pass
and fallbacks in SDAG/GlobalISEL and FastISel. The latter now assert
on the intrinsics.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
