The analysis mode gives the user a clustered view of the measurement results and
highlights any inconsistencies with the checked-in data.

Summary:
Removing the full structor and replacing all usages with the base one
can degrade debug quality as it will leave the debugger unable to locate
the full object structor. This is apparent when evaluating an expression
in the debugger which requires constructing an object of class which has
had this optimization applied to it. When compiling the expression, we
pretend that the class and its methods have been defined in another
compilation unit, so the expression compiler assumes the structor
definition must be available. This didn't use to be the case for
structors with internal linkage. Less aggressive optimizations like
emitting the full structor as an alias remain in place, as they do not
cause the structor symbol to disappear completely.
This improves debug quality on non-darwin platforms (darwin does not
have -mconstructor-aliases on by default, so it is spared these
problems) and enable us to remove some workarounds from LLDB which attempt to
mitigate this issue.

Summary:
We used to query the index when completing after class qualifiers,
e.g. 'ClassName::^'. We should not do that for the same reasons we
don't query the index for member access expressions.

Summary:
This fixes a regression introduced by `r331857` where we stop the search for
the End token as soon as we hit a non-scope-closer, which prematurely stops before
semicolons for example, which should otherwise be considered as part of the unbreakable tail.

If a symbol with an undefined version in a DSO is not going to be
exported into the dynamic symbol table then do not give an error message
for the missing version. This can happen with the --exclude-libs option
which implicitly gives all symbols in a static library the local version.
This matches the behavior of ld.gold and is exploited by the Bionic
dynamic linker on Arm.

Summary:
The first foray into merging debug info into the echo tests.
- Add bindings to Module::getModuleFlagsMetadata() in the form of LLVMCopyModuleFlagsMetadata
- Add the opaque type LLVMModuleFlagEntry to represent Module::ModuleFlagEntry
- Add accessors for LLVMModuleFlagEntry's behavior, key, and metadata node.

If we're using default rounding mode we can let __builtin_convertvector to generate an fpextend. This matches 128 and 256 bit.
If we're using the version that takes an explicit rounding mode argument we would need to look at the immediate to see if its CUR_DIRECTION.

Summary:
This change allows for handling the in-memory data associated with the
FDR mode implementation through the new `__xray_log_process_buffers`
API. With this change, we can now allow users to process the data
in-memory of the process instead of through writing files.
This for example allows users to stream the data of the FDR logging
implementation through network sockets, or through other mechanisms
instead of saving them to local files.
We introduce an FDR-specific flag, for "no_file_flush" which lets the
flushing logic skip opening/writing to files.
This option can be defaulted to `true` when building the compiler-rt
XRay runtime through the `XRAY_FDR_OPTIONS` preprocessor macro.

We can use direct C code for these that will use uitofp and insertelement instructions.
For the versions that take an explicit rounding mode we can't do this.

Pavel Labath found this patch is incomplete and racy. I think there needs to
be some more mutexes even before considering DW_TAG_partial_unit.

This pass is
a) broken.
b) r600 specific.
Fixing (a) is a bit more non-trivial, but fixing (b)
is easy. Move this pass to being R600 only for now.
This pass does pass all the unit tests, however clang
no longer generates code that looks like the unit test
input, so fixing the pass requires fixing the tests and
the pass as one, and checking it works with clang still.

These intrinsics work exactly as all other atomic_fetch_* intrinsics and allow to create *atomicrmw* with ordering.
