Only introduce the SDKSettings.plist dependency in modules/PCH files that don't depend on any other modules or PCH files.

llvm-svn: 177542

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.

Updated from r177211.

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

This reverts commit 06091513c283c863296f01cc7c2e86b56bb50d02.

The code is obviously wrong, but the trivial fix causes
inefficient code generation on X86. Somebody with more
knowledge of the code needs to take a look here.

case of order propagation during isel.

Thanks Owen for the suggestion!

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.

This allows us to test Polly and the Polly optimizer without actually doing
code generation at the end. By enabling this option, we can also measure the
compile time overhead due to code generation and the cost of LLVM optimizing the
newly generated code.t

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.

256 blocks (which is 512 in reallity) seems to be too big cache,
reducing the size reduces memory consumption but does not degrade performance.
