When displaying the macro backtrace, ignore some of the backtraces that do not
provide extra information to the diagnostic. Typically, if the problem is
entirely contained within a macro argument, the macro expansion is often not
needed. Also take into account SourceRange's attached to the diagnostic when
selecting which backtraces to ignore. Two previous test cases have also been
updated.

AliasAnalysis.
Same as the other commits, the TLI access from an alias analysis is
going away and isn't very clean -- it is better to explicitly mark the
dependencies.

just depend on it directly.
This was particularly frustrating because there was a really wide
mixture of using a member variable and re-extracting it from the AA that
happened to be around. I think the result is much more clear.
I've also deleted all of the pointless null checks and used references
across the APIs where I could to make it explicit that this cannot be
null in a useful fashion.

Summary:
D11924 implemented part of the floating-point comparisons, this patch implements the rest:
* Tell ISelLowering that all booleans are either 0 or 1.
* Expand the eq/ne/lt/le/gt/ge floating-point comparisons to the canonical ones (similar to what Mips32r6InstrInfo.td does).
* Add tests for ord/uno.
* Add tests for ueq/one/ult/ule/ugt/uge.
* Fix existing comparison tests to remove the (res & 1) code, which setBooleanContents stops from generating.

relying on sneaking it out of its AliasAnalysis.
This abuse of AA (to shuffle TLI around rather than explicitly depending
on it) is going away with my refactor of AA.

r243382 changed the behavior to always require a set of memchecks to be
passed to LoopVer. This change restores the prior behavior as an
alternative to the new behavior. This allows the checks to be
implicitly taken from the LAA object.

The fix for this is in LLVM but it depends on how clang handles the alias
attribute, so add a test to the clang tests to make sure everything works
together as expected.

r242520 was reverted in r244313 as the expected behaviour of the alias
attribute in C is that the alias has the same size as the aliasee. However
we can re-introduce adding the size on the alias when the aliasee does not,
from a source code or object perspective, exist as a discrete entity. This
happens when the aliasee is not a symbol, or when that symbol is private.

On Mach-O emitting aliases for the variables that make up a MergedGlobals
variable can cause problems when linking with dead stripping enabled so don't
do that, except for external variables where we must emit an alias.

removes a corner case in tests that don't set the diagnostic consumer.
In tests, it is good, not to set the diagnostic consumer so that Clang's
parsing diagnostics are still displayed in the test output and only
ClangTidy's output is analyzed differently.

On x86/x86_64 read only watchpoints aren't supported. Fall back
to read/write watchpoints in that case.
Note: Logic should be added to ignore the watchpoint hit when
occurred because of a write.

The ASAN callbacks are public symbols so we can search for them
with reading only the symbol table (not the debug info). Whit this

On android .oat files (compiled java code) don't have symbol
information but on SDK 23+ it can be generated by the oatdump tool
(based on the dex information).
This CL adds logic to download this information and store it in the

While the compile time is not affected by this patch much it will
allow us to look at all translated expressions after the SCoP is build
in a convenient way. Additionally, bigger SCoPs or SCoPs with
repeating complicated expressions might benefit from the cache later
on.

This change has three major advantages:
- The ScopInfo becomes smaller.
- It allows to use the SCEVAffinator from outside the ScopInfo.
- A member object allows state which in turn allows e.g., caching.

In order to find the llvm-obj directory it has to be (or a soft link
to it) at one of the following locations:
${POLLY_SRC_DIR}/build
${POLLY_SRC_DIR}.build
${POLLY_SRC_DIR}-build
s/${POLLY_SRC_DIR}/src/build
Alternatively, the environment variable $POLLY_BIN_DIR can point to it.
