Sema: allow imaginary constants via GNU extension if UDL overloads not present.
C++14 added user-defined literal support for complex numbers so that you can
write something like "complex<double> val = 2i". However, there is an existing
GNU extension supporting this syntax and interpreting the result as a _Complex

This changes parsing so that such literals are interpreted in terms of C++14's

[CodeView] Eliminate redundant hashes and allocations.
When writing field list records, we would construct a temporary
type serializer that shared a bump ptr allocator with the rest
of the application, so anything allocated from here would live
forever. Furthermore, this temporary serializer had all the
properties of a full blown serializer including record hashing
and de-duplication.
These features are required when you're merging multiple type
streams into each other, because different streams may contain
identical records, but records from the same type stream will
never collide with each other. So all of this hashing was
unnecessary.
To solve this, two fixes are made:
1) The temporary serializer keeps its own bump ptr allocator
instead of sharing a global one. When it's finished, all of
its memory is freed.
2) Instead of using the same temporary serializer for the life
of an entire type stream, we use it only for the life of a single
field list record and delete it when the field list record is
completed. This way the hash table will not grow as other
records from the same type stream get inserted. Further improvements
could eliminate hashing entirely from this codepath.
This reduces the link time by 85% in my test, from 1 minute to 9
seconds.

[PDB] Hash types up front when merging types instead of using StringMap
Summary:
First, StringMap uses llvm::HashString, which is only good for short
identifiers and really bad for large blobs of binary data like type
records. Moving to `DenseMap<StringRef, TypeIndex>` with some tricks for
memory allocation fixes that.
Unfortunately, that didn't buy very much performance. Profiling showed
that we spend a long time during DenseMap growth rehashing existing
entries. Also, in general, DenseMap is faster when the keys are small.
This change takes that to the logical conclusion by introducing a small
wrapper value type around a pointer to key data. The key data contains a
precomputed hash, the original record data (pointer and size), and the
type index, which is the "value" of our original map.
This reduces the time to produce llvm-as.exe and llvm-as.pdb from ~15s
on my machine to 3.5s, which is about a 4x improvement.

[IR] Switch AttributeList to use an array for O(1) access
Summary:
Before this change, AttributeLists stored a pair of index and
AttributeSet. This is memory efficient if most arguments do not have
attributes. However, it requires doing a search over the pairs to test
an argument or function attribute. Profiling shows that this loop was
0.76% of the time in 'opt -O2' of sqlite3.c, because LLVM constantly
tests values for nullability.
This was worth about 2.5% of mid-level optimization cycles on the
sqlite3 amalgamation. Here are the full perf results:
https://reviews.llvm.org/P7995
Here are just the before and after cycle counts:
```
$ perf stat -r 5 ./opt_before -O2 sqlite3.bc -o /dev/null
13,274,181,184 cycles # 3.047 GHz ( +- 0.28% )
$ perf stat -r 5 ./opt_after -O2 sqlite3.bc -o /dev/null
12,906,927,263 cycles # 3.043 GHz ( +- 0.51% )
```
This patch *does not* change the indices used to query attributes, as
requested by reviewers. Tracking whether an index is usable for array
indexing is a huge pain that affects many of the internal APIs, so it
would be good to come back later and do a cleanup to remove this
internal adjustment.

Add support for new (3.0.11+) swigs
Summary:
A change in swig 3.0.9 has caused it to generate modules incompatible

fix this problem, so use that. Support for older versions of swig remains

[mips] Make checks in CodeGen/mips-varargs.c less fragile
This test was failing on our fork of clang because it was not capturing
[[ARG]] in the N32 case. Therefore it used the value from the last function
which does not always have to be the same. All other cases were already
capturing ARG so this appears to be an oversight.
The test now uses -enable-var-scope to prevent such errors in the future.

This change increases the number of AES instruction pairs generated on

[LV] Report multiple reasons for not vectorizing under allowExtraAnalysis
The default behavior of -Rpass-analysis=loop-vectorizer is to report only the
first reason encountered for not vectorizing, if one is found, at which time the
vectorizer aborts its handling of the loop. This patch allows multiple reasons
for not vectorizing to be identified and reported, at the potential expense of
additional compile-time, under allowExtraAnalysis which can currently be turned
on by Clang's -fsave-optimization-record and opt's -pass-remarks-missed.
Removed from LoopVectorizationLegality::canVectorize() the redundant checking
and reporting if we CantComputeNumberOfIterations, as LAI::canAnalyzeLoop() also
does that. This redundancy is caught by a lit test once multiple reasons are
reported.
