[InstCombine] Add missing constant check (#170068)
`cast<Constant>` is not guarded by a type check during canonicalization
of predicates. This patch adds a type check in the outer if to avoid the
crash. `dyn_cast` may introduce another nested if, so I just use
`isa<Constant>` instead.
Address the crash reported in

[lldb][debugserver] Return shared cache filepath in jGetSharedCacheInfo (#168474)
Add a "shared_cache_path" key-value to the jGetSharedCacheInfo response,
if we can fetch the shared cache path.
If debugserver and the inferior process are running with the same shared
cache UUID, there is a simple SPI to get debugserver's own shared cache
filepath and we will return that.
On newer OSes, there are SPI we can use to get the inferior process'
shared cache filepath, use that if necessary and the SPI are available.
The response for the jGetSharedCacheInfo packet will now look like
{"shared_cache_base_address":6609256448,"shared_cache_uuid":"B69FF43C-DBFD-3FB1-B4FE-A8FE32EA1062","no_shared_cache":false,"shared_cache_private_cache":false,"shared_cache_path":"/System/Volumes/Preboot/Cryptexes/OS/System/Library/dyld/dyld_shared_cache_arm64e"}
when we have the full information about the shared cache in the
inferior. There are three possible types of responses:

[AMDGPU] Verify dominance when rewriting spills to registers
Rev1: Updated condition to check for "joint domination", i.e. no reload
is reachable from entry without reaching a store to the same slot. Still
working on reduced test or unit test.
When performing spill elimination in the AGPR copy rewrite pass it was
possible to see spill reloads that were not jointly dominated by any
store. This caused invalid MIR to be generated where vreg uses were not
dominated by defs. This patch adds a joint dominance check before
rewriting spills.
