The current implementation of the pattern matching optimizations relies on the
initial ordering of dimensions. Otherwise, it can produce the miscompilation

This patch helps to restore the initial ordering of dimensions by recreating

[analyzer] Reland r299544 "Add a modular constraint system to the CloneDetector"

Hopefully fix crashes by unshadowing the variable.

Original commit message:

A big part of the clone detection code is functionality for filtering clones and
clone groups based on different criteria. So far this filtering process was
hardcoded into the CloneDetector class, which made it hard to understand and,
ultimately, to extend.

This patch splits the CloneDetector's logic into a sequence of reusable
constraints that are used for filtering clone groups. These constraints
can be turned on and off and reodreder at will, and new constraints are easy
to implement if necessary.

Unit tests are added for the new constraint interface.

This is a refactoring patch - no functional change intended.

[ELF] Pad x86 executable sections with 0xcc int3 instructions

Executable sections should not be padded with zero by default. On some
architectures, 0x00 is the start of a valid instruction sequence, so can confuse
disassembly between InputSections (and indeed the start of the next InputSection
in some situations). Further, in the case of misjumps into padding, padding may
start to be executed silently.

On x86, the "0xcc" byte represents the int3 trap instruction. It is a single
byte long so can serve well as padding. This change switches x86 (and x86_64) to
use this value for padding in executable sections, if no linker script directive
overrides it. It also puts the behaviour into place making it easy to change the
behaviour of other targets when desired. I do not know the relevant instruction
sequences for trap instructions on other targets however, so somebody should add
this separately.

Because the old behaviour simply wrote padding in the whole section before
overwriting most of it, this change also modifies the padding algorithm to write
padding only where needed. This in turn has caused a small behaviour change with
regards to what values are written via Fill commands in linker scripts, bringing
it into line with ld.bfd. The fill value is now written starting from the end of
the previous block, which means that it always starts from the first byte of the
fill, whereas the old behaviour meant that the padding sometimes started mid-way
through the fill value. See the test changes for more details.

[lsan] Avoid segfaults during threads destruction under high load

This patch addresses two issues:

* It turned out that suspended thread may have dtls->dtv_size == kDestroyedThread (-1)
and LSan wrongly assumes that DTV is available. This leads to SEGV when LSan tries to
iterate through DTV that is invalid.
* In some rare cases GetRegistersAndSP can fail with errno 3 (ESRCH). In this case LSan
assumes that the whole stack of a given thread is available. This is wrong because ESRCH
can indicate that suspended thread was destroyed and its stack was unmapped. This patch
properly handles ESRCH from GetRegistersAndSP in order to avoid invalid accesses to already

[XRay] [compiler-rt] Unwriting FDR mode buffers when functions are short.

Summary:
"short" is defined as an xray flag, and buffer rewinding happens for both exits
 and tail exits.

 I've made the choice to seek backwards finding pairs of FunctionEntry, TailExit
 record pairs and erasing them if the FunctionEntry occurred before exit from the
 currently exiting function. This is a compromise so that we don't skip logging
 tail calls if the function that they call into takes longer our duration.

 This works by counting the consecutive function and function entry, tail exit
 pairs that proceed the current point in the buffer. The buffer is rewound to
 check whether these entry points happened recently enough to be erased.

 It is still possible we will omit them if they call into a child function that
 is not instrumented which calls a fast grandchild that is instrumented before
 doing other processing.

in StackColoring.

To be on the safe side, remove all lifetime markers even in the original
code version (they have never been copied to the optimized version)
to ensure that no path to the entry block will cross a
llvm.lifetime.start.

The same principle applies to paths the a function return and the
llvm.lifetime.end marker, so we remove them as well.

This fixes llvm.org/PR32251.
