Revert "unique_ptr-ify ownership of ASTConsumers"

This reverts commit r213307.

Reverting to have some on-list discussion/confirmation about the ongoing
direction of smart pointer usage in the LLVM project.

PR20346: fix aggregate initialization / template instantiation bug:

If, during the initial parse of a template, we perform aggregate initialization
and form an implicit value initialization for an array type, then when we come
to instantiate the template and redo the initialization step, we would try to
match the implicit value initialization up against an array *element*, not to
the complete array.

Remarkably, we've had this bug since ~the dawn of time, but only noticed it
recently.

Fix parsing certain kinds of strings in the MS section pragmas

We were crashing on the relevant test case inputs.  Also, refactor this
code a bit so we can report failure and slurp the pragma tokens without
returning a diagnostic id.  This is more consistent with the rest of the
parser and sema code.

Mark the vtable used when defining implicit copy and move ctors

I don't think other implicit members like copy assignment and move
assignment require this treatment, because they should already be
operating on a constructed object.

Fixes PR20351.

[modules] Fix macro hiding bug exposed if:

 * A submodule of module A is imported into module B
 * Another submodule of module A that is not imported into B exports a macro
 * Some submodule of module B also exports a definition of the macro, and
   happens to be the first submodule of B that imports module A.

In this case, we would incorrectly determine that A's macro redefines B's
macro, and so we don't need to re-export B's macro at all.

This happens with the 'assert' macro in an LLVM self-host. =(

[AArch64] Implement Clang CLI interface proposal about "-march".

1. Revert "Add default feature for CPUs on AArch64 target in Clang"
at r210625. Then, all enabled feature will by passed explicitly by
-target-feature in -cc1 option.

2. Get "-mfpu" deprecated.

3. Implement support of "-march". Usage is:
    -march=armv8-a+[no]feature
  For instance, "-march=armv8-a+neon+crc+nocrypto". Here "armv8-a" is
  necessary, and CPU names are not acceptable. Candidate features are
  fp, neon, crc and crypto. Where conflicting feature modifiers are
  specified, the right-most feature is used.

4. Implement support of "-mtune". Usage is:
    -march=CPU_NAME
  For instance, "-march=cortex-a57". This option will ONLY get
  micro-architectural feature enabled specifying to target CPU,
  like "+zcm" and "+zcz" for cyclone. Any architectural features
  WON'T be modified.

5. Change usage of "-mcpu" to "-mcpu=CPU_NAME+[no]feature", which is
  an alias to "-march={feature of CPU_NAME}+[no]feature" and
  "-mtune=CPU_NAME" together. Where this option is used in conjunction
  with -march or -mtune, those options take precedence over the
  appropriate part of this option.

[ARM] Fix AAPCS regression caused by r211898

r211898 introduced a regression where a large struct, which would
normally be passed ByVal, was causing padding to be inserted to
prevent the backend from using some GPRs, in order to follow the
AAPCS. However, the type of the argument was not being set correctly,
so the backend cannot align 8-byte aligned struct types on the stack.

The fix is to not insert the padding arguments when the argument is
being passed ByVal.
