Rehashing the ExplodedNode table is very expensive. The hashing
itself is expensive, and the general activity of iterating over the
hash table is highly cache unfriendly. Instead, we guess at the
eventual size by using the maximum number of steps allowed. This
generally avoids a rehash. It is possible that we still need to
rehash if the backlog of work that is added to the worklist
significantly exceeds the number of work items that we process. Even
if we do need to rehash in that scenario, this change is still a
win, as we still have fewer rehashes that we would have prior to
this change.
For small work loads, this will increase the memory used. For large
work loads, it will somewhat reduce the memory used. Speed is
significantly increased. A large .C file took 3m53.812s to analyze
prior to this change. Now it takes 3m38.976s, for a ~6% improvement.

Crash reported in PR28023 is caused by the fact that non-type template
parameters are found by tag name lookup. In the code provided in that PR:
template<int V> struct A {
struct B {
template <int> friend struct V;
};
};
the template parameter V is found when lookup for redeclarations of 'struct V'
is made. Latter on the error about shadowing of 'V' is emitted but the semantic
context of 'struct V' is already determined wrong: 'struct A' instead of
translation unit.
The fix moves the check for shadowing toward the beginning of the method and
thus prevents from wrong context calculations.
This change fixes PR28023.

Given the following C++:
```
void foo();
void foo() __attribute__((enable_if(false, "")));
bool bar() {
auto P = foo;
return P == foo;
}
```
We'll currently happily (and correctly) resolve `foo` to the `foo`
overload without `enable_if` when assigning to `P`. However, we'll
complain about an ambiguous overload on the `P == foo` line, because
`Sema::CheckPlaceholderExpr` doesn't recognize that there's only one
`foo` that could possibly work here.
This patch teaches `Sema::CheckPlaceholderExpr` how to properly deal
with such cases.
Grepping for other callers of things like
`Sema::ResolveAndFixSingleFunctionTemplateSpecialization`, it *looks*
like this is the last place that needed to be fixed up. If I'm wrong,
I'll see if there's something we can do that beats what amounts to

Summary:
32-bit CPU's default to O32. 64-bit CPU's default to N64. The default CPU
(mips32r2/mips64r2) still depends on the arch so there's no functional
change when the CPU isn't specified but commands like:
clang -target mips-mti-linux-gnu -mips64r2
will now default to a 64-bit ABI like our gcc toolchains do* instead of
asserting in the backend**.
Other vendors (including Triple::UnknownVendor) still derive the default
ABI from the arch.
* Although not the same one as our gcc toolchains, clang has historically
defaulted to N64 where gcc defaults to N32.
** Mixing O32 and a 64-bit CPU causing assertions is a long-standing bug.

When we import a module that defines a builtin identifier from prefix header and
precompile the prefix header, the macro information related to the identifier
is lost.
If we don't precompile the prefix header, the source file can still see the
macro information. The reason is that we write out the identifier in the pch
but not the macro information since the macro is not defined locally.
This is related to r251565. In that commit, if we read a builtin identifier from
a module that wasn't "interesting" to that module, we will still write it out to
a PCH that imports that module.
The fix is to write exported module macros for PCH as well.

According to the gcc headers, intel intrinsics docs and msdn codegen the _mm_store1_pd (and its _mm_store_pd1 equivalent) should use an aligned pointer - the clang headers are the only implementation I can find that assume non-aligned stores (by storing with _mm_storeu_pd).
Additionally, according to the intel intrinsics docs and msdn codegen the _mm_store1_ps (_mm_store_ps1) requires a similarly aligned pointer.
This patch raises the alignment requirements to match the other implementations by calling _mm_store_ps/_mm_store_pd instead.
I've also added the missing _mm_store_pd1 intrinsic (which maps to _mm_store1_pd like _mm_store_ps1 does to _mm_store1_ps).
As a followup I'll update the llvm fast-isel tests to match this codegen.
