Rafael Espindola e2c2461a6b Merge identical strings.
This avoids the need to have reserve and addString in sync.

We avoid hashing the global symbols again. This means that we don't
merge a global symbol that has the same name as some other string, but
that doesn't seem very common. The string table size is the same in
clang an scylladb with or without hashing global symbols again.

Ahmed Bougacha 53010a0d5b [AArch64] Fix i64 nontemporal high-half extraction.
Since we only have pair - not single - nontemporal store instructions,
we have to extract the high part into a separate register to be able
to use them.

When the initial nontemporal codegen support was added, I wrote the
extract using the nonsensical UBFX [0,32[.
Use the correct LSR form instead.

Easwaran Raman 30a93c1848 Lower inlining threshold when the caller has minsize attribute.
When the caller has optsize attribute, we reduce the inlinining threshold
to OptSizeThreshold (=75) if it is not already lower than that. We don't do
the same for minsize and I suspect it was not intentional. This also addresses
a FIXME regarding checking optsize attribute explicitly instead of using the
right wrapper.

Manman Ren 494ee5b049 Class Property: change PropertyMap to include isClassProperty.
PropertyMap used to map IdentifierInfo (name of the property) to
ObjcPropertyDecl *. Now that a class property can have the same name as
an instance property, we change PropertyMap to map a pair <IdentifierInfo *,
unsigned> to ObjcPropertyDecl *.

Also update a few places from iterating over instance_properties to
iterating over all properties.

Reid Kleckner c62e379d22 [CodeView] Use assembler directives for line tables
Adds a new family of .cv_* directives to LLVM's variant of GAS syntax:

- .cv_file: Similar to DWARF .file directives

- .cv_loc: Similar to the DWARF .loc directive, but starts with a
  function id. CodeView line tables are emitted by function instead of
  by compilation unit, so we needed an extra field to communicate this.
  Rather than overloading the .loc direction further, we decided it was
  better to have our own directive.

- .cv_stringtable: Emits the codeview string table at the current
  position. Currently this just contains the filenames as
  null-terminated strings.

- .cv_filechecksums: Emits the file checksum table for all files used
  with .cv_file so far. There is currently no support for emitting
  actual checksums, just filenames.

This moves the line table emission code down into the assembler.  This
is in preparation for implementing the inlined call site line table
format. The inline line table format encoding algorithm requires knowing
the absolute code offsets, so it must run after the assembler has laid
out the code.

David Majnemer collaborated on this patch.

Manman Ren 581c2b9d46 Check for frontend errors after releasing the Builder.
Frontend can emit errors when releaseing the Builder. If there are errors before
or when releasing the Builder, we reset the module to stop here before invoking
the backend.

Before this commit, clang will continue to invoke the backend and backend can
crash.

Jonathan Peyton 7d45451a0d Fix task dependency performance problem
In: http://lists.llvm.org/pipermail/openmp-dev/2015-August/000858.html, a
performance issue was found with libomp's task dependencies.  The task
dependencies hash table has an issue with collisions. The current table size is
a power of two. This combined with the current hash function causes a large
number of collisions to occurr. Also, the current size (64) is too small for
larger applications so the table size is increased.

This patch creates a two level hash table approach for task dependencies. The
implicit task is considered the "master" or "top-level" task which has a large
static sized hash table (997), and nested tasks will have smaller hash
tables (97). Prime numbers were chosen to help reduce collisions.

Devin Coughlin de21767a4d [analyzer] Suppress nullability warnings in copy, mutableCopy, and init families.
There are multiple, common idioms of defensive nil-checks in copy,
mutableCopy, and init methods in ObjC. The analyzer doesn't currently have the
capability to distinguish these idioms from true positives, so suppress all
warnings about returns in those families. This is a pretty blunt suppression
that we should improve later.
