Chandler Carruth 6e479322aa Remove LSR's use of the random AddrMode struct. These variables were
already in a class, just inline the four of them. I suspect that this
class could be simplified some to not always keep distinct variables for
these things, but it wasn't clear to me how given the usage so I opted
for a trivial and mechanical translation.

This removes one of the two remaining users of a header in include/llvm
which does nothing more than define a 4 member struct.

Chandler Carruth 26c59fa870 Switch the SCEV expander and LoopStrengthReduce to use
TargetTransformInfo rather than TargetLowering, removing one of the
primary instances of the layering violation of Transforms depending
directly on Target.

This is a really big deal because LSR used to be a "special" pass that
could only be tested fully using llc and by looking at the full output
of it. It also couldn't run with any other loop passes because it had to
be created by the backend. No longer is this true. LSR is now just
a normal pass and we should probably lift the creation of LSR out of
lib/CodeGen/Passes.cpp and into the PassManagerBuilder. =] I've not done
this, or updated all of the tests to use opt and a triple, because
I suspect someone more familiar with LSR would do a better job. This
change should be essentially without functional impact for normal
compilations, and only change behvaior of targetless compilations.

The conversion required changing all of the LSR code to refer to the TTI
interfaces, which fortunately are very similar to TargetLowering's
interfaces. However, it also allowed us to *always* expect to have some
implementation around. I've pushed that simplification through the pass,
and leveraged it to simplify code somewhat. It required some test
updates for one of two things: either we used to skip some checks
altogether but now we get the default "no" answer for them, or we used
to have no information about the target and now we do have some.

I've also started the process of removing AddrMode, as the TTI interface
doesn't use it any longer. In some cases this simplifies code, and in
others it adds some complexity, but I think it's not a bad tradeoff even
there. Subsequent patches will try to clean this up even further and use
other (more appropriate) abstractions.

Yet again, almost all of the formatting changes brought to you by
clang-format. =]

Daniel Jasper 206df73417 Prefer not to break after assignments.
This addresses llvm.org/PR14830.

Before:
unsigned Cost =
    TTI.getMemoryOpCost(I->getOpcode(), VectorTy, SI->getAlignment(),
                        SI->getPointerAddressSpace());
CharSourceRange LineRange =
    CharSourceRange::getTokenRange(TheLine.Tokens.front().Tok.getLocation(),
                                   TheLine.Tokens.back().Tok.getLocation());

After:
unsigned Cost = TTI.getMemoryOpCost(I->getOpcode(), VectorTy,
                                    SI->getAlignment(),
                                    SI->getPointerAddressSpace());
CharSourceRange LineRange = CharSourceRange::getTokenRange(
                                TheLine.Tokens.front().Tok.getLocation(),
                                TheLine.Tokens.back().Tok.getLocation());

This required rudimentary changes to static initializer lists, but we
are not yet formatting them in a reasonable way. That will be done in a
subsequent patch.

Daniel Jasper da16db3f9a Do not break before "0" in pure virtual function declarations.
Before:
virtual void write(ELFWriter *writer, OwningPtr<FileOutputBuffer> &buffer) =
    0

After:
virtual void write(ELFWriter *writerrr,
                   OwningPtr<FileOutputBuffer> &buffer) = 0;

This addresses llvm.org/PR14815.

To implement this I introduced a line type during parsing and moved the
definition of TokenType out of the struct for increased readability.
Should have done the latter in a separate patch, but it would be hard to
pull apart now.

Chandler Carruth b7e60f6844 Merge the unused header file for LoopVectorizer into the source file.
This makes the loop vectorizer match the pattern followed by roughly all
other passses. =]

Notably, this header file was braken in several regards: it contained
a using namespace directive, global #define's that aren't globaly
appropriate, and global constants defined directly in the header file.

As a side benefit, lots of the types in this file become internal, which
will cause the optimizer to chew on this pass more effectively.

Chandler Carruth 7383bfd67e Switch BBVectorize to directly depend on having a TTI analysis.
This could be simplified further, but Hal has a specific feature for
ignoring TTI, and so I preserved that.

Also, I needed to use it because a number of tests fail when switching
from a null TTI to the NoTTI nonce implementation. That seems suspicious
to me and so may be something that you need to look into Hal. I worked
it by preserving the old behavior for these tests with the flag that
ignores all target info.

Chandler Carruth 04ece8623e Fix a slew of indentation and parameter naming style issues. This 80% of
this patch brought to you by the tool clang-format.

I wanted to fix up the names of constructor parameters because they
followed a bit of an anti-pattern by naming initialisms with CamelCase:
'Tti', 'Se', etc. This appears to have been in an attempt to not overlap
with the names of member variables 'TTI', 'SE', etc. However,
constructor arguments can very safely alias members, and in fact that's
the conventional way to pass in members. I've fixed all of these I saw,
along with making some strang abbreviations such as 'Lp' be simpler 'L',
or 'Lgl' be the word 'Legal'.

However, the code I was touching had indentation and formatting somewhat
all over the map. So I ran clang-format and fixed them.

I also fixed a few other formatting or doxygen formatting issues such as
using ///< on trailing comments so they are associated with the correct
entry.

There is still a lot of room for improvement of the formating and
cleanliness of this code. ;] At least a few parts of the coding
standards or common practices in LLVM's code aren't followed, the enum
naming rules jumped out at me. I may mix some of these while I'm here,
but not all of them.

We would format:
  #define A \
    int f(a); int i;
as
  #define A \
    int f(a);\
    int i

The fix will break up macro definitions that could fit a line, but hit
the last column; fixing that is more involved, though, as it requires
looking at the following line.

Manuel Klimek c74d292229 Fix layouting of single-line-comments preceded by an escaped newline.
Previously, we'd format
  int i;\
  // comment
as
  int i; // comment

thus the raw token text of the comment doesn't start with "//".

Manuel Klimek ef92069940 Fix layouting of tokens with a leading escaped newline.
If a token follows directly on an escaped newline, the escaped newline
is stored with the token. Since we re-layout escaped newlines, we need
to treat them just like normal whitespace - thus, we need to increase
the whitespace-length of the token, while decreasing the token length
(otherwise the token length contains the length of the escaped newline
and we double-count it while indenting).

Chandler Carruth 0b4ef9cedc Make SimplifyCFG simply depend upon TargetTransformInfo and pass it
through as a reference rather than a pointer. There is always *some*
implementation of this available, so this simplifies code by not having
to test for whether it is available or not.

Further, it turns out there were piles of places where SimplifyCFG was
recursing and not passing down either TD or TTI. These are fixed to be
more pedantically consistent even though I don't have any particular
cases where it would matter.
