[bazel] Remove unnecessary textual_hdrs usage (#191072)
textual_hdrs is supposed to be used for header files that aren't
standalone, which isn't the case for these mlir headers. Being in
textual_hdrs excludes them from header parsing, which means
layering_check results aren't entirely valid. I'm going to try and
enable header parsing on these targets in a follow up change.
geom: Make g_waitidle() wait for orphaned providers
This is motivated by the following race in the ZFS zvol code.
When a zvol is created, we create a GEOM-backed zvol, which results in a
/dev/zvol/<zvol path> device file, created by GEOM::dev. If volmode=dev
is specified, zvol_set_volmode_impl() will wither the GEOM, then create
a device file with the same name. This sometimes fails because
g_wither_geom() is asynchronous, so we end up trying to create a device
file while the old one still exists. I want to fix this by adding a
g_waitidle() call to zvol_os_remove_minor().
g_waitidle() is not sufficient: GEOM::dev does not destroy the device
until g_dev_orphan() is called. (In fact the device destruction is
asynchronous too, but the delist_dev() call is sufficient to address
this race.) So, I propose modifying g_waitidle() to block until
orphaned providers are processed.

[libc++] Optionally support filecheck and split-file (#165769)
This patch adds optional support for FileCheck and split-file in
libc++'s test suite. Whether FileCheck / split-file is available
can be queried using Lit features.
This should make it possible to test several things that were
previously impossible to test, especially for specific code
generation.
Supersedes #65917 and #188283
[ObjCARC] Optimize MayAutorelease by skipping over pools (#188583)
This enables the ARC optimizer to remove autoreleasePoolPush/Pop pairs
that were previously retained. By skipping over nested autorelease
pools, MayAutorelease now correctly recognizes that autoreleases
contained within an inner pool do not escape, allowing the removal of
outer pool boundaries.
