Fix redundant comparison in gcc::Common::ConstructJob.

We were checking "Arch == llvm::Triple::x86_64 || Arch
== llvm::Triple::x86_64", but the rhs should actually check for
powerpc64.

Found while experimenting with a potential new Clang warning.

Improve formatting of function types in template parameters.

Before: A<int * (int)>;
After:  A<int *(int)>;

Don't remove all indentation when in #defines.

Otherwise, this can become hard to read.

Before: #define A \
        case 1:
After:  #define A \
           case 1:

Add extra indentation for multiline comparisons.

This seems to be generally more desired.

Before:
if (aaaaaaaa &&
    bbbbbbbb >
    cccccccc) {}
After:
if (aaaaaaaa &&
    bbbbbbbb >
        cccccccc) {}

Also: Some formatting cleanup on clang-format's files.

Reduce penalty for breaks after "(" for functions with parameters.

Before:
  aaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
                    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
                    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
After:
  aaaaaaaaaaaaaaaaa(
      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa + aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

Do not consider comments when adjusting to local indent style.

Before (when only reformatting "int b"):
int a; // comment
       // comment
       int b;

After:
int a; // comment
       // comment
int b;

This also fixes llvm.org/PR15433.

Remove assertion that can be triggered on bad input.

clang-format can't do anything useful, so it should leave the remainder
of the line unchanged, but it should not assert/segfault.

Exploit this-return of a callsite in a this-return function.

For constructors/desctructors that return 'this', if there exists a callsite
that returns 'this' and is immediately before the return instruction, make
sure we are using the return value from the callsite.

We don't need to keep 'this' alive through the callsite. It also enables
optimizations in the backend, such as tail call optimization.

Enhance debug info namespace test to check for context/scope reference

The #line directive is mostly for backend testing (keeping these files matching
should simplify maintenance somewhat) though the corresponding backend test
improvement/update doesn't verify the file information directly just yet.
Coming in a later iteration.
