Summary:
For targets I'm not familiar with, I've automatically made the "default to 1 for each resource" behaviour explicit in the td files.
For more obvious cases, I've ventured a fix.
Some notes:
- Exynos is especially fishy.
- AArch64SchedThunderX2T99.td had some truncated entries. If I understand correctly, the person who wrote that interpreted the ResourceCycle as a range. I made the decision to use the upper/lower bound for consistency with the 'Latency' value. I'm sure there is a better choice.
- The change to X86ScheduleBtVer2.td is an NFC, it just makes values more explicit.

Summary:
Caching is now handled by ClangdLSPServer and hidden behind the
GlobalCompilationDatabase interface. This simplifies ClangdServer.
This change also removes the SkipCache flag from addDocument,
which is now obsolete.
No behavioral changes are intended, the clangd binary still caches the
compile commands on the first read.

WebAssembly depends on attributes.h which includes attributes.inc.
Unless cmake explicitly specifies this dependency, the .inc file
is sometimes generated after the build tries to use it.

Summary:
This method was not correct for entries in DWO files as it assumed it
could just add up the CU and DIE offsets to get the absolute DIE offset.
This is not correct for the DWO files, as here the CU offset will
reference the skeleton unit, whereas the DIE offset will be the offset
in the full unit in the DWO file.
Unfortunately, this means that we are not able to determine the absolute
DIE offset using the information in the .debug_names section alone,
which means we have to offload some of this work to the users of this
class.
To demonstrate how this can be done, I've added/fixed the ability to
lookup entries using accelerator tables in DWO files in llvm-dwarfdump.
To make this happen, I've needed to make two extra changes in other
classes:
- made the DWARFContext method to lookup a CU based on the section
offset public. I've needed this functionality to lookup a CU, and this
seems like a useful thing in general.
- made DWARFUnit::getDWOId call extractDIEsIfNeeded. Before this, the
DWOId was filled in only if the root DIE happened to be parsed
before we called the accessor. Since the lazy parsing is supposed to
happen under the hood, calling extractDIEsIfNeeded seems appropriate.

IndVarSimplify sometimes makes transforms basing on users that are trivially dead. In particular,
if DCE wasn't run before it, there may be a dead `sext/zext` in loop that will trigger widening
transforms, however it makes no sense to do it.
This patch teaches IndVarsSimplify ignore the mist trivial cases of that.

This reverts commit r334543.
My understanding is, that commit is intended to make the llvm-build
invocation have a correct "--enable-optional-components" value, but:
- it already has a value: it's quoted in the command line a few lines
below, and, if I hack llvm-build to print sys.argv, it does look correct:
-- llvm-build output: ['.../utils/llvm-build/llvm-build',
'--native-target', 'X86', '--enable-targets', 'X86;ARM;AArch64',
'--enable-optional-components', '',
'--write-library-table',
'.../build/tools/llvm-config/LibraryDependencies.inc',
'--write-cmake-fragment', '.../build/LLVMBuild.cmake']
- the " " string seems to evaluate to TRUE in CMake (*sigh*), so this
basically force-enables LLVM_USE_INTEL_JITEVENTS, regardless of the
value of the option.
On Darwin, JITEvents is not supported, so this bypasses that OS check
but is guaranteed to fail later.

When running with linker GC (`-opt:ref`), defined imported symbols that
are referenced but then dropped by GC end up with their `Location`
member being nullptr, which means `getChunk()` returns nullptr for them
and attempting to call `getChunk()->getOutputSection()` causes a crash
from the nullptr dereference. Check for `getChunk()` being nullptr and
bail out early to avoid the crash.

getEndPath is a problematic API, because it's not clear when it's called
(hint: not always at the end of the path), it crashes at runtime with
more than one non-nullptr returning implementation, and diagnostics
internal depend on it being called at some exact place.
However, most visitors don't actually need that: all they want is a
function consistently called after all nodes are traversed, to perform
finalization and to decide whether invalidation is needed.
