Pass the input vector through SimplifyDemandedBits as we only need the sign bit from each vector element of MOVMSK
We'd probably get more hits if SimplifyDemandedBits was better at handling vectors...

Adds the assembler aliases for the floating point instructions
which can be mapped to a single canonical instruction. The missing
pseudo instructions (flw, fld, fsw, fsd) are marked as TODO. Other
things, like for example PCREL_LO, have to be implemented first.
This patch builds upon D40902.

Summary:
This makes it possible to run an arbitrary matcher on the value
contained within the Expected<T> object.
To do this, I've needed to fully spell out the matcher, instead of using
the shorthand MATCHER_P macro.
The slight gotcha here is that standard template deduction will fail if
one tries to match HasValue(47) against an Expected<int &> -- the
workaround is to use HasValue(testing::Eq(47)).
The explanations produced by this matcher have changed a bit, since now
we delegate to the nested matcher to print the value. Since these don't
put quotes around the value, I've changed our PrintTo methods to match.

When an instruction mnemonic contains a '.', we usually name the instruction
with a _ in that place. e.g. fadd.s -> FADD_S.
This patch updates RISCVInstrInfoC.td to do the same, e.g. c.nop -> C_NOP.
Also includes some minor formatting changes in RISCVInstrInfoC.td to better
align it with the formatting conventions in the rest of the backend.

r320413 triggered cmake configure failures when building with
-DLLVM_OPTIMIZED_TABLEGEN=True and with LLVM_EXPERIMENTAL_TARGETS_TO_BUILD set
(e.g. to RISCV). This is because that patch moved to passing through
LLVM_TARGETS_TO_BUILD, and at that point LLVM_EXPERIMENTAL_TARGETS_TO_BUILD
has been merged in to it. LLVM_EXPERIMENTAL_TARGETS_TO_BUILD must be also be
passed through to avoid errors like below:

Summary:
- when the diagnostic has an explicit range, we prefer that
- if the diagnostic has a fixit, its RemoveRange is our next choice
- otherwise we try to expand the diagnostic location into a whole token.
(inspired by VSCode, which does this client-side when given an empty range)
- if all else fails, we return the zero-width range as now.
(clients react in different ways to this, highlighting a token or a char)
- this includes the off-by-one fix from D40860, and borrows heavily from it

Most of the targets don't need the scheduler class enum.
I have an X86 scheduler model change that causes some names in the enum to become about 18000 characters long. This is because using instregex in scheduler models causes the scheduler class to get named with every instruction that matches the regex concatenated together. MSVC has a limit of 4096 characters for an identifier name. Rather than trying to come up with way to reduce the name length, I'm just going to sidestep the problem by not including the enum in X86.

This change makes XRay print the log file output only when the verbosity
level is higher than 0. It reduces the log spam in the default case when
we want XRay running silently, except when there are actual
fatal/serious errors.
We also update the documentation to show how to get the information
after the change to the default behaviour.

Now two classes are responsible for verification: one of them can track GC
pointers and know whether a pointer is relocated or not and another based on
that information can verify uses of GC pointers.

Summary:
This patch tries to vectorize loads of consecutive memory accesses, accessed
in non-consecutive or jumbled way. An earlier attempt was made with patch D26905
which was reverted back due to some basic issue with representing the 'use mask' of
jumbled accesses.
This patch fixes the mask representation by recording the 'use mask' in the usertree entry.

Summary:
This change makes the call site creation more general if any of the
arguments is predicated on a condition in the call site's predecessors.
If we find a callsite, that potentially can be split, we collect the set
of conditions for the call site's predecessors (currently only 2
predecessors are allowed). To do that, we traverse each predecessor's
predecessors as long as it only has single predecessors and record the
condition, if it is relevant to the call site. For each condition, we
also check if the condition is taken or not. In case it is not taken,
we record the inverse predicate.
We use the recorded conditions to create the new call sites and split
the basic block.
This has 2 benefits: (1) it is slightly easier to see what is going on
(IMO) and (2) we can easily extend it to handle more complex control
flow.
