Revert some Hexagon builtin commits to match reverts done to LLVM in
r155047. See the LLVM log for the primary motivation:
  http://llvm.org/viewvc/llvm-project?rev=155047&view=rev

Primary commit r154828:
  - Several issues were raised in review, and fixed in subsequent
    commits.
  - Follow-up commits also reverted, and which should be folded into the
    original before reposting:
    - r154837: Re-add the 'undef BUILTIN' thing to fix the build.
    - r154928: Fix build warnings, re-add (and correct) header and
      license
    - r154937: Typo fix.

Please resubmit this patch with the relevant LLVM resubmission.

PR 12586: Fix assert while running libc++ testsuite: deal with exception
specifications on member function templates of class templates and other such
nested beasties. Store the function template from which we are to instantiate
an exception specification rather than trying to deduce it. Plus some
additional test cases.

Make setVisibility private and change users to mergeVisibility. This is
currently a nop as those users are the first merge or are a merge
of a hidden explicit visibility, which always wins in the current
implementation.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155095 91177308-0d34-0410-b5e6-96231b3b80d8
Move the point in the code where we handle -fvisibility=hidden. With
the current implementation this should be a nop as explicit visibility
takes precedence in mergeVisibility.

The location chosen is such that attributes checked above it can force
a symbol to be default. For example, an attribute is the variable or function.
Attributes checked after this point, can only make the visibility more
restrictive. An attribute in a type for example.

The explicit bit in LV already tracks exactly the same information as
DHasExplicitVisibility. Simplify the code a bit.

Check ConsiderGlobalVisibility before using -fvisibility.

Now that we check visibility attributes in an appropriate order,
there is no need for mergeVisibily to ever increase the visibility. Not
doing so lets us replace an incorrect use of mergeVisibilityWithMin. The
testcase

struct HIDDEN RECT {
  int top;
};
DEFAULT RECT foo = {0};

shows that we should give preference to one of the attributes instead of
keeping the minimum. We still get this testcase wrong because mergeVisibily
handles two explicit visibilities incorrectly, but this is a step in the
right direction.

In mergeVisibilityWithMin, let an implicit hidden symbol take precedence over
an explicit default one. This means that with -fvisibility hidden we
now produce a hidden symbol for

template <typename T>
class DEFAULT foo {
  void bar() {}
};
class zed {};
template class foo<zed>;

This matches the behaviour of gcc 4.7.

In mergeVisibility, if we already have an explicit visibility, keep it.
This fixes the included testcase and lets us simplify the code a bit. It
does require using mergeWithMin when merging class information to its
members. Expand the comments to explain why that works.
