[llvm-readelf]Revert --dyn-symbols behaviour to make it GNU compatible, and add new --hash-symbols switch for old behaviour
In r287786, the behaviour of --dyn-symbols in llvm-readelf (but not
llvm-readobj) was changed to print the dynamic symbols as derived from
the hash table, rather than to print the dynamic symbol table contents
directly. The original change was initially submitted without review,
and some comments were made on the commit mailing list implying that the
new behavious is GNU compatible. I argue that it is not:
1) It does not include a null symbol.
2) It prints the symbols based on an order derived from the hash
table.
3) It prints an extra column indicating which bucket it came from.
This could break parsers that expect a fixed number of columns,
with the first column being the symbol index.
4) If the input happens to have both .hash and .gnu.hash section, it
prints interpretations of them both, resulting in most symbols
being printed twice.
5) There is no way of just printing the raw dynamic symbol table,
because --symbols also prints the static symbol table.
This patch reverts the --dyn-symbols behaviour back to its old behaviour
of just printing the contents of the dynamic symbol table, similar to
what is printed by --symbols. As the hashed interpretation is still
desirable to validate the hash table, it puts it under a new switch
"--hash-symbols". This is a no-op on all output forms except for GNU
output style for ELF. If there is no hash table, it does nothing,
unlike the previous behaviour which printed the raw dynamic symbol
table, since the raw dynsym is available under --dyn-symbols.
The yaml input for the test is based on that in
test/tools/llvm-readobj/demangle.test, but stripped down to the bare
minimum to provide a valid dynamic symbol.
Note: some LLD tests needed updating. I will commit a separate patch for
those.

[X86] Change avx512 COMPRESS and EXPAND lowering to use a single masked node instead of expand/compress+select.
Summary:
For compress, a select node doesn't semantically reflect the behavior of the instruction. The mask would have holes in it, but the resulting write is to contiguous elements at the bottom of the vector.
Furthermore, as far as the compressing and expanding is concerned the behavior is depended on the mask. You can't just have an expand/compress node that only reads the input vector. That node would have no meaning by itself.
This all only works because we pattern match the compress/expand+select back to the instruction. But conceivably an optimization of the select could break the pattern and leave something meaningless.
This patch modifies the expand and compress node to take the mask and passthru as additional inputs and gets rid of the select all together.

[X86][BtVer2] Update the WriteLoad latency.
r327630 introduced new write definitions for float/vector loads.
Before that revision, WriteLoad was used by both integer/float (scalar/vector)
load. So, WriteLoad had to conservatively declare a latency to 5cy. That is
because the load-to-use latency for float/vector load is 5cy.
Now that we have dedicated writes for float/vector loads, there is no reason why
we should keep the latency of WriteLoad to 5cy. At the moment, WriteLoad is only
used by scalar integer loads only; we can assume an optimstic 3cy latency for
them.
This patch changes that latency from 5cy to 3cy, and regenerates the affected

[SCEV][NFC] Introduces expression sizes estimation
This patch introduces the field `ExpressionSize` in SCEV. This field is
calculated only once on SCEV creation, and it represents the complexity of
this SCEV from arithmetical point of view (not from the point of the number
of actual different SCEV nodes that are used in the expression). Roughly
saying, it is the number of operands and operations symbols when we print this
SCEV.
A formal definition is following: if SCEV `X` has operands
`Op1`, `Op2`, ..., `OpN`,
then
Size(X) = 1 + Size(Op1) + Size(Op2) + ... + Size(OpN).
Size of SCEVConstant and SCEVUnknown is one.
Expression size may be used as a universal way to limit SCEV transformations
for huge SCEVs. Currently, we have a bunch of options that represents various
limits (such as recursion depth limit) that may not make any sense from the
point of view of a LLVM users who is not familiar with SCEV internals, and all
these different options pursue one goal. A more general rule that may
potentially allow us to get rid of this redundancy in options is "do not make
transformations with SCEVs of huge size". It can apply to all SCEV traversals
and transformations that may need to visit a SCEV node more than once, hence
they are prone to combinatorial explosions.
This patch only introduces SCEV sizes calculation as NFC, its utilization will
be introduced in follow-up patches.

[libFuzzer][MSVC] Make Sanitizer Coverage MSVC-compatible
Summary:
Make Sanitizer Coverage work when compiled work when compiler-rt
is compiled with MSVC.
The previous solution did not work for MSVC because MSVC tried to
align the .SCOV$CZ section even though we used
__declspec(align(1)) on its only symbol:
__stop___sancov_cntrs.
Because the counter array is composed
of 1 byte elements, it does not always end on an 8 or 4 byte
boundary. This means that padding was sometimes added to
added to align the next section, .SCOV$CZ.
Use a different strategy now: instead of only instructing
the compiler not to align the symbol, make the section
one byte long by making its only symbol a uint8_t, so that
the linker won't try to align it.
