There are cases when we have to merge TBAA access tags with the
same base access type, but different final access types. For
example, accesses to different members of the same structure may
be vectorized into a single load or store instruction. Since we
currently assume that the tags to merge always share the same
final access type, we incorrectly return a tag that describes an
access to one of the original final access types as the generic
tag. This patch fixes that by producing generic tags for the
common type and not the final access types of the original tags.

Previously these pseudo instructions were not guarded by ISA, so their

My fix is conservative and will make us return may-alias instead.
The test case is:
check(gep(x, 0), n, gep(x, n), -1) with n == sizeof(x)
Here, the first value accesses the whole object, but the second access
doesn't access anything. The semantics of -1 is read until the end of the
object, which in this case means read nothing.
No test case, since isn't trivial to exploit this one, but I've proved it correct.

The thread name was not followed by a space, which meant it was glued to
the log message. I also align the name as we do that with other log
fields. I align it to 16 chars instead of llvm::max_thread_name(), as
that can be 64 on darwin, which is rather long. If anybody feels
differently about that, we can change it.

Summary:
This test was failing in various configurations on linux in a fairly
unpredictible way. The success depended on whether the c++ abi library
was linked in statically or not and how well was the linker able to
strip parts of it. This introduces additional code to the "dummmy" test
executable, which ensures that all parts of the library needed to
evaluate the expressions are always present.

Summary:
Adjusted PrintingPolicy inside code completion to avoid printing some
redundant name qualifiers.
Before this change, typedefs that were written unqualified in source
code were printed with qualifiers in completion. For example, in the
following code
struct foo {
typedef int type;
type method();
};
completion item for `method` had return type of `foo::type`, even
though the original code used `type` without qualifiers.
After this change, the completion item has return type `type`, as
originally written in the source code.
Note that this change does not suppress qualifiers written by the
user. For example, in the following code
typedef int type;
struct foo {
typedef int type;
::type method(foo::type);
};
completion item for `method` has return type of `::type` and
parameter type of `foo::type`, as originally written in the source
code.

rL162640 introduced CodeGenTarget::guessInstructionProperties. If a target
sets guessInstructionProperties=0 in its FooInstrInfo, tablegen will error if
it has to guess properties from patterns. Unfortunately,
guessInstructionProperties=0 can't be used with current upstream LLVM as
instructions in the TargetOpcode namespace are always included and sometimes
have inferred properties for mayLoad, mayStore, and hasSideEffects. This patch
provides the simplest possible fix to this problem, setting default values for
these fields in the TargetOpcode scope. There is no intended functional
change, as the explicitly set properties should match what was previously
inferred. A number of the instructions had hasSideEffects=1 inferred
unintentionally. This patch makes it explicit, while future patches (such as
D37097) correct the property.

Some of the AMDGPU stack addressing modes require knowing the sign
bit is zero. We used to accomplish this by custom lowering
frame indexes, and then putting an AssertZext around a
TargetFrameIndex. This required specifically looking for
the AssextZext + frame index pattern which was moderately
disgusting. The same could probably be accomplished
with a target specific node, but would still
require special handling of frame indexes.

This is (probably) not required by LSP, but at least one buggy client wants it.

Summary:
This change allows yaml input to control the order of implicitly added sections
(`.symtab`, `.strtab`, `.shstrtab`). The order is controlled by adding a
placeholder section of the given name to the Sections field.
This change is to support changes in D39582, where it is desirable to control
the location of the `.dynsym` section.
This reapplied version fixes:
1. use of a function call within an assert
2. failing lld test which has an unnamed section
Additionally, one more test to cover the unnamed section failure.
