[llvm-symbolizer] Support debug file lookup using build ID
Build ID is a protocol for looking up debug files that's already
supported by various tools including debuggers. For example, when
locating debug files, gdb would check the following directories:
- /usr/lib/debug/.build-id/ab/cdef1234.debug
- /usr/bin/ls.debug
- /usr/bin/.debug/ls.debug
- /usr/lib/debug/usr/bin/ls.debug
llvm-symbolizer currently consults all of these except for build ID
based one. This patch implements support for build ID lookup. The set of
debug directories to search is specified by the new option:
--debug-file-directory, whose name matches the debug-file-directory
variable used by gdb for the same purpose.

Commit e11df585800596df2052a475f6191673b8f1a5c1 by Jason Molenda
Upstream debugserver arm64e support.
The changes are minor; primarily debugserver needs to go through
accessor functions/macros when changing pc/fp/sp/lr, and debugserver
needs to clear any existing pointer auth bits from values in two cases.
debugserver can fetch the number of bits used for addressing from a
sysctl, and will include that in the qHostInfo reply.  Update qHostInfo
documentation to document it.

[llvm] Fixing MIRVRegNamerUtils to properly handle 2+
An interplay of code from D70210, along with code from the
Value-Numbering-esque hash-based namer from D70210, as well as some
crusty code from the original MIR-Canon code lead to multiple causes of
failure when canonicalizing or renaming vregs for MIR with multiple
basic blocks. This patch fixes those issues while deleting some no
longer needed code and adding a nice diamond test case to boot.

[analyzer] Fix more ObjC accessor body farms after 2073dd2d.
Fix a crash when constructing a body farm for accessors of a property
that is declared and @synthesize'd in different (but related) interfaces
with the explicit ivar syntax.
This is a follow-up for 0b58b80e.
