The simplify-libcalls pass implemented a doInitialization hook to infer
function prototype attributes for well-known functions.  Given that the
simplify-libcalls pass is going away *and* that the functionattrs pass
is already in place to deduce function attributes, I am moving this logic
to the functionattrs pass.  This approach was discussed during patch
review:

comparing type_info names, since the latter have better uniqueness guarantees
in practice.

This test case will measure memory usage and expression timings in frame zero and at higher frames.

Fixed the ValidOffsetForDataOfSize() to use simpler logic. Fixed DataExtractor::BytesLeft() to return the correct value.

llvm-svn: 177616

Simplify the logic for DNBDataRef::ValidOffsetForDataOfSize() and DNBDataRef::ValidOffset() functions.

of the same size.

This isn't necessary & with the next change to LLVM the DW_TAG_file_type entry
won't be emitted at all - only the raw filename/directory pair, so match on
that directly instead.

They are generally faster (at least not slower) than post-inc, post-dec.

 * libclang_rt-san-* is sanitizer_common, and is linked in only if no other
   sanitizer runtime is present.
 * libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on
   a C++ ABI library, and is always linked in.
 * libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a
   C++ ABI library, and is only linked in when linking a C++ binary.

The Darwin ubsan runtime is unchanged.

For more details, see Clang change r177605.

 * libclang_rt-san-* is sanitizer_common, and is linked in only if no other
   sanitizer runtime is present.
 * libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on
   a C++ ABI library, and is always linked in.
 * libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a
   C++ ABI library, and is only linked in when linking a C++ binary.

This change also switches us to using -whole-archive for the ubsan runtime
(which is made possible by the above split), and switches us to only linking
the sanitizer runtime into the main binary and not into DSOs (which is made
possible by using -whole-archive).

The motivation for this is to only link a single copy of sanitizer_common
into any binary. This is becoming important now because we want to share
more state between multiple sanitizers in the same process (for instance,
we want a single shared output mutex).

The Darwin ubsan runtime is unchanged; because we use a DSO there, we don't
need this complexity.

Native Windows Python will do line ending translation by default, which
we don't want in bash scripts.  If we're not native Windows Python, then
'b' is ignored.

It's not yet clear if these instructions need a more careful model.

This is used for all the expensive system instructions.

Making a manual mode of operation for measurements, where you can manually call start() and stop() instead of using the function-call syntax
This is especially useful to take measurements that span multiple test steps, or where you need to have different operations fall under the same measurement

An example of use is in the formatters perf test case

When computing the demanded bits of Load SDNodes, make sure that we are looking at the loaded-value operand and not the ptr result (in case of pre-inc loads).

ArrayRef<uint8_t>::equals(); lowers to a byte compare loop :(.

TODO: Figure out if we are getting hash collisions, or just have a lot of equal
content. Also test if crypto hashing the content instead of full compare is
better.

- After moving logic recognizing vector shift with scalar amount from
  DAG combining into DAG lowering, we declare to customize all vector
  shifts even vector shift on AVX is legal. As a result, the cost model
  needs special tuning to identify these legal cases.

track the EH FDEs for the functions in a module to using a
RangeDataVector, a more light-weight data structure that only refers
to File addresses.  Makes the initial FDE scan about 3x faster, uses
less memory.
