Peter Szecsi 07964fbdcb [analyzer] MisusedMovedObjectChecker: More precise warning message
Added new enum in order to differentiate the warning messages on "misusing" into
3 categories: function calls, moving an object, copying an object. (At the
moment the checker gives the same message in case of copying and moving.)

Additional test cases added as well.

Craig Topper 0692ca4bd2 [X86] Remove invalid code from LowerVSELECT.
This code attempted to say that v8i16/v16i16 VSELECT is legal if BWI and VLX are enabled, but the only way we could reach this point is if the condition was not a vXi1 type. Which means it really wasn't legal.

We don't have any tests that exercise this code. So I'm hoping it wasn't really reachable.

Peter Szecsi 65f8f83a74 [analyzer] MisusedMovedObjectChecker: Fix false positive on state-resetting, handling method calls on base-class sub-objects
An earlier solution from Artem r315301 solves the reset problem, however, the
reports should be handled the same way in case of method calls. We should not
just report the base class of the object where the method was defined but the
whole object.

Fixed false positive which came from not removing the subobjects in case of a
state-resetting function. (Just replaced the State->remove(...) call to
removeFromState(..) which was defined exactly for that purpose.)

Some minor typos fixed in this patch as well which did not worth a whole new
patch in my opinion, so included them here.

Sanjay Patel b049173157 [SimplifyCFG] use pass options and remove the latesimplifycfg pass
This is no-functional-change-intended.

This is repackaging the functionality of D30333 (defer switch-to-lookup-tables) and 
D35411 (defer folding unconditional branches) with pass parameters rather than a named
"latesimplifycfg" pass. Now that we have individual options to control the functionality,
we could decouple when these fire (but that's an independent patch if desired). 

The next planned step would be to add another option bit to disable the sinking transform
mentioned in D38566. This should also make it clear that the new pass manager needs to
be updated to limit simplifycfg in the same way as the old pass manager.

Peter Szecsi 1496d188a0 [analyzer] LoopUnrolling: check the bitwidth of the used numbers (pr34943)
The loop unrolling feature aims to track the maximum possible steps a loop can
make. In order to implement this, it investigates the initial value of the 
counter variable and the bound number. (It has to be known.)
These numbers are used as llvm::APInts, however, it was not checked if their
bitwidths are the same which lead to some crashes.
This revision solves this problem by extending the "shorter" one (to the length
of the "longer" one).

Craig Topper 49687104d6 [PartialInlineLibCalls] Teach PartialInlineLibCalls to honor nobuiltin, properly check the function signature, and check TLI::has
Summary:
We shouldn't do this transformation if the function is marked nobuitlin.

We were only checking that the return type is floating point, we really should be checking the argument types and argument count as well. This can be accomplished by using the other version of getLibFunc that takes the Function and not just the name.

We should also be checking TLI::has since sqrtf is a macro on Windows.

Fixes PR32559.

Dean Michael Berris e8fec1955a [XRay][compiler-rt] Remove more STL dependenices from FDR mode
Summary:
This change removes dependencies on STL types:

  - std::aligned_storage -- we're using manually-aligned character
    buffers instead for metadata and function records.

  - std::tuple -- use a plain old struct instead.

This is an incremental step in removing all STL references from the
compiler-rt implementation of XRay (llvm.org/PR32274).

Rui Ueyama bda337a8d8 Rename isInCurrentDSO -> isInCurrentOutput.
DSO is short for dynamic shared object, so the function name was a
little confusing because it sounded like it didn't work when we were
a creating statically-linked executable or something.

What we mean by "DSO" here is the current output file that we are
creating. Thus the new name. Alternatively, we could call it the current
ELF module, but "module" is a overloaded word, so I avoided that.

Reid Kleckner 2e87a21c7c [MS] Allow access to ambiguous, inaccessible direct bases
Summary:
Clang typically warns that in the following class hierarchy, 'A' is
inaccessible because there is no series of casts that the user can
write to access it unambiguously:
  struct A { };
  struct B : A { };
  struct C : A, B { };

MSVC allows the user to convert from C* to A*, though, and we've
encountered this issue in the latest Windows SDK headers.

This patch allows this conversion when -fms-compatibility is set and
adds a warning for it under -Wmicrosoft-inaccessible-base.
