Summary:
This patch improves detection of incomplete code for protos and text protos.
This is especially important for text protos in raw string literals, since they
might be partial strings concatenated, and we'd like to disable formatting in
these cases.

Summary:
Added instructions for contiguous stores, ST1, with scalar+imm addressing
modes and corresponding tests. The patch also adds parsing of
'mul vl' as needed for the VL-scaled immediate.
This is patch [6/6] in a series to add assembler/disassembler support for
SVE's contiguous ST1 (scalar+imm) instructions.

When we're dealing with virtual (memory) threads created by the OS
plugins, there's no guarantee that the real thread and the backing
thread share a protocol ID. Instead, we should iterate over the memory
threads to find the virtual thread that is backed by the current real
thread.

Summary:
When performing a synchronous resume, the API mutex is held until the
process is stopped. This is fine, except for when the OS plugins are processing
an event before the main thread is aware of it, in which case we end up with a
deadlock because in the internal thread we acquire a resource lock first, and
then wait for the API lock, while in the main thread we do the opposite, we
already hold the API mutex but are now waiting for the event mutex to handle
the event.
This patch fixes this by relaxing the need for the API lock in the OS plugins.
We can get away with this because we now this code is executed in the main
thread. As stated in the comment above, we just want to ensure nobody else
messes with the API while we're making a change. In theory it's possible that
the main thread would release the lock while we're executing the function, but
prevent this would require a more structural solution (which we want, but do
not have today).
The same workaround was already present, but this patch generalizes it to the
whole file.
This will allow me to re-land r329891.

Summary:
The fold added in D45108 did not account for the fact that
the and instruction is commutative, and if the mask is a variable,
the mask variable and the fold variable may be swapped.
I have noticed this by accident when looking into [[ https://bugs.llvm.org/show_bug.cgi?id=6773 | PR6773 ]]
This extends/generalizes that fold, so it is handled too.

- shorten architecture SOURCES definitions as most fit 1 line/arch
- comment in English what's where, and where the different .a come from
(using only the word "runtime" in the comment isn't useful, since the
CMake primitive itself says "runtime" in its name)
- skip unsupported architectures quickly, to avoid extra indentation

Summary:
LSP is using Line & column as symbol position, clangd needs to transfer file
offset to Line & column when sending results back to LSP client, which is a high
cost, especially for finding workspace symbol -- we have to read the file
content from disk (if it isn't loaded in memory).
Saving these information in the index will make the clangd life eaiser.

MIPS ABI requires creation of the MIPS_RLD_MAP dynamic tag for non-PIE
executables only and MIPS_RLD_MAP_REL tag for both PIE and non-PIE
executables. The patch skips definition of the MIPS_RLD_MAP for PIE
files and defines MIPS_RLD_MAP_REL.
The MIPS_RLD_MAP_REL tag stores the offset to the .rld_map section
relative to the address of the tag itself.

various scripting environments.
This is related to llvm.org/PR37066, a follow-up to D45474.

Summary:
This change addresses http://llvm.org/PR36926 by allowing users to pick
which instrumentation bundles to use, when instrumenting with XRay. In
particular, the flag `-fxray-instrumentation-bundle=` has four valid
values:
- `all`: the default, emits all instrumentation kinds
- `none`: equivalent to -fnoxray-instrument
- `function`: emits the entry/exit instrumentation
- `custom`: emits the custom event instrumentation
These can be combined either as comma-separated values, or as
repeated flag values.

Objective-C's @synchronize synchronization primitive uses calls to objc_sync_enter and objc_sync_exit runtime functions. In most cases, they end up just calling pthread_mutex_lock/pthread_mutex_unlock, but there are some cases where the synchronization from pthread_mutex_lock/pthread_mutex_unlock interceptors isn't enough. Let's add explicit interceptors for objc_sync_enter and objc_sync_exit to handle all cases.

IsStackOverflow only treats accesses within 512 bytes of SP as stack-overflow. This should really be the size of a page instead.
The scariness_score_test.cc triggers stack overflow with frames that are even larger than a page, which can also trigger a fault that will not be recognized as stack-overflow. Let's just use smaller frames.
