NetBSD uses `long int` for `intptr_t` on ARM. This was changed in SVN
r316046, referenced against other compilers. However, NetBSD's
reference was incorrect as the current clang behaviour is more
up-to-date. Restore the original behaviour for that target.

GCC tries to shorten system headers in depfiles using its real path
(resolving components like ".." and following symlinks). Mimic this
feature to ensure that the Ninja build tool detects the correct
dependencies when a symlink changes directory levels, see
https://github.com/ninja-build/ninja/issues/1330
An option to disable this feature is added in case "these changed header
paths may conflict with some compilation environments", see
https://gcc.gnu.org/ml/gcc-patches/2012-09/msg00287.html
Note that the original feature request for GCC
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52974) also included paths
preprocessed output (-E) and diagnostics. That is not implemented now
since I am not sure if it breaks something else.

In function GetIntrinsic, not all types are covered. Types double and long long are missed, type long is wrongly treated same as int, it should be same as long long. These problems cause compiler crashes when compiling code in PR31161. This patch fixed the problem.

instantiation declarations if they are usable from constant expressions.
We are permitted to instantiate in these cases, and required to do so in order
to have an initializer available for use within constant evaluation.

Summary:
This patch enables sorting the full block of using declarations when
some line is affected.

This patch has the following changes
A new flag "-mhvx-length={64B|128B}" is introduced to specify the length of the vector.
Previously we have used "-mhvx-double" for 128 Bytes. This adds the target-feature "+hvx-length{64|128}b"
The "-mhvx" flag must be provided on command line to enable HVX for Hexagon. If no -mhvx-length flag
is specified, a default length is picked from the arch mentioned in this priority order from either -mhvx=vxx
or -mcpu. For v60 and v62 the default length is 64 Byte. For unknown versions, the length is 128 Byte. The
-mhvx flag adds the target-feature "+hvxv{hvx_version}"
The 64 Byte mode is soon going to be deprecated. A warning is emitted if 64 Byte is enabled. A warning is
still emitted for the default 64 Byte as well. This warning can be suppressed with a -Wno flag.
The "-mhvx-double" and "-mno-hvx-double" flags are deprecated. A warning is emitted if the driver sees
them on commandline. "-mhvx-double" is an alias to "-mhvx-length=128B"
The compilation will error out if -mhvx-length is specified with out an -mhvx/-mhvx= flag
The macro HVX_LENGTH is defined and is set to the length of the vector.
Eg: #define HVX_LENGTH 64
The macro HVX_ARCH is defined and is set to the version of the HVX.
Eg: #define HVX_ARCH 62

Summary:
* Support rename alias.
* Add unittests for renaming alias.
* Don't generate fixes for the SourceLocations that are invalid or in temporary
buffer, otherwise crash would be happened when generating AtomicChanges.

It'd be better that they are #cmakedefine01 rather than #cmakedefine.
(#if FOO rather than #if defined(FOO))

Darwin and OpenBSD are the only platforms which use `long int` for
`__INTPTR_TYPE__`. The other platforms use `int` in 32-bit, and `long
int` on 64-bit (except for VMS and Windows which are LLP64). Adjust the
type definitions to match the platform definitions. We now generate the
same definition as GCC on all the targets.

Remove an option to use a reference type (on by default!) since a
non-reference type is always needed for creating expressions, functions
with multiple boolean parameters are very hard to use, and in general it
was just a booby trap for further crashes.
Furthermore, generalize call_once test case to fix some of the crashes mentioned
https://bugs.llvm.org/show_bug.cgi?id=34869
Also removes std::call_once crash.

Use the new helper methods to get the underlying type for NSUInteger,
NSInteger types. This avoids spreading the knowledge of the underlying

Currently clang assumes the temporary variables emitted during
codegen of atomic builtins have address space 0, which
is not true for target triple amdgcn---amdgiz and causes invalid
bitcasts.

The main change is that now we generate TBAA info before
constructing the resulting lvalue instead of constructing lvalue
with some default TBAA info and fixing it as necessary
afterwards. We also keep the TBAA info close to lvalue base info,
which is supposed to simplify their future merging.
This patch should not bring in any functional changes.
This is part of D38126 reworked to be a separate patch to
simplify review.
