Pattern has source location by itself. After adding a trivial method to
retrieve it, it's unnecessary to pair a source location for CHECK-NOT patterns.
One thing revised after this is the diagnostic info is more accurate by
pointing to the start of the CHECK-NOT pattern instead of the end of the
CHECK-NOT pattern. E.g. diagnostic message previously looks like

    <stdin>:1:1: error: CHECK-NOT: string occurred!
    test
    ^
    test.txt:1:16: note: CHECK-NOT: pattern specified here
    CHECK-NOT: test
                   ^

is changed to

    <stdin>:1:1: error: CHECK-NOT: string occurred!
    test
    ^
    test.txt:1:12: note: CHECK-NOT: pattern specified here
    CHECK-NOT: test
               ^

latency for certain models of the Intel Atom family, by converting

- Adds unique enums for ymm registers to the ABI and the POSIX register context.
- Reworks the register context data structures to support a union of FXSAVE and XSAVE
--- Allows the same code base to deal with the FPU independent of the availability of AVX.
- Determine if AVX is supported by attempting to read XSAVE using ptrace.
--- Support an extended register set for avx registers if available.
- Provide a mechanism to assemble/parse register halves into a single ymm buffer for use with RegisterValue.
--- Reworked Read/WriteRegister routines to read/write/parse ymm registers.

Adds tests for ymm register write with read-back, and expressions involving ymm registers.
- Tests vary depending on the availability of an avx register set.

Thanks to Daniel and Matt for their reviews.

When we find a friend declaration we have to skip transparent contexts for doing
lookups, but we should not skip them when inserting the new decl if the lookup
found nothing.

Fixes PR15841.

Summary:
This is modelled on the Mach-O linker options implementation and should
support a Clang implementation of #pragma comment(lib/linker).

Deeply nested expressions basically break clang-format's memoization.
This patch slightly improves the situations and makes expressions like

  aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(
      aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(
          aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(
              aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(aaaaa(
                  aaaaa(aaaaa())))))))))))))))))))))))))))))))))))))));

Since the relocation iterator walks only the relocations in one section, we
can just use a pointer and avoid fetching information about the section at
every reference.

getRelocationAddress is for dynamic libraries and executables,
getRelocationOffset for relocatable objects.

Mark the getRelocationAddress of COFF and MachO as not implemented yet. Add a
test of ELF's. llvm-readobj -r now prints the same values as readelf -r.

Instead, we check for one line extern "C" context in linkage computation and
when deciding if a variable is a definition.

This hopefully completes the transition to having "as written" semantics for
hasExternalStorage.

Fix constant folding for one lane vector types. Constant folding one lane vector types not returns a vector instead of a scalar.

This enables formattings like:

  #define A   \
    int aaaa; \
    int b;    \
    int ccc;  \
    int dddddddddd;

Enabling this for Google/Chromium styles only as I don't know whether it
is desired for Clang/LLVM.

This includes the following fixes:
 - Implement 4 subtly different variants of qualifier mangling and use them
   in what I believe are the right places.
 - Fix handling of array types.  Previously we were always decaying them,
   which is wrong if the type appears as a template argument, pointee,
   referent etc.
Fixes PR13182.

In Process::ProcessEventData::DoOnRemoval, we need to handle the case where NO thread has a stop reason
specially, and make sure we stop.  This shouldn't happen, but if it does, the user will probably want to
see it.
