Daniel Malea 5d3e8a62e0 Remove distinction between Apple/Linux for Process run locks:
- Played with the current dual run lock implementation for a few days, noticed
  no regressions, so enabling in trunk so we see if any problems are detected
  by buildbots.

Peter Collingbourne 6f4be19b57 [nolibc] Change internal syscall API to remove reliance on libc's errno.
This change moves to a model where the error value of a system call is
potentially contained in the return value itself rather than being
implicit in errno.  The helper function internal_iserror can be used
to extract the error value from a return value.  On platforms other
than Linux/x86_64 this still uses errno, but other platforms are free
to port their error handling to this new model.

Daniel Jasper d69fc77b9e Improve line breaking in binary expressions.
If the LHS of a binary expression is broken, clang-format should also
break after the operator as otherwise:
- The RHS can be easy to miss
- It can look as if clang-format doesn't understand operator precedence

Before:
bool aaaaaaaaaaaaaaaaaaaaa = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa !=
                                 bbbbbbbbbbbbbbbbbb && ccccccccc == ddddddddddd;
After:
bool aaaaaaaaaaaaaaaaaaaaa =
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa != bbbbbbbbbbbbbbbbbb &&
    ccccccccc == ddddddddddd;

As an additional note, clang-format would also be ok with the following
formatting, it just has a higher penalty (IMO correctly so).
bool aaaaaaaaaaaaaaaaaaaaa = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa !=
                                 bbbbbbbbbbbbbbbbbb &&
                             ccccccccc == ddddddddddd;

Reid Kleckner e43f0fea15 Forward #pragma comment(lib/linker) through as flags metadata
Summary:
Most of this change is wiring the pragma all the way through from the
lexer, parser, and sema to codegen.  I considered adding a Decl AST node
for this, but it seemed too heavyweight.

Mach-O already uses a metadata flag called "Linker Options" to do this
kind of auto-linking.  This change follows that pattern.

LLVM knows how to forward the "Linker Options" metadata into the COFF
.drectve section where these flags belong.  ELF support is not
implemented, but possible.

This is related to auto-linking, which is http://llvm.org/PR13016.

Peter Collingbourne 5829a98c48 [nolibc] Disable the GCC stack protector when building sanitizer runtimes.
This is the first in a sequence of changes designed to eliminate the
libc dependency in sanitizer_common.  The main motivation for these
changes is to be able to provide an alternative for the current
interceptor-based technique for instrumenting functions in libc.
In this new technique, we compile libc with instrumentation.  This has
the potential advantages of being more accurate than interception and
reducing the amount of custom code required for each libc function.
As a side effect of this, we cannot depend on libc in the sanitizer
runtime due to mutual dependency issues.

This change disables the GCC stack protector, which introduces a libc
dependency and is enabled by default in Ubuntu.

Daniel Jasper 0f0234e16e Change indentation of multi-line nested name specifiers.
Before:
aaaaaaaa::
    aaaaaaaa::
    aaaaaaaa();
After:
aaaaaaaa::
    aaaaaaaa::

The reason for the change is that:
a) we are not sure which is better
b) it is a really rare edge case
c) it simplifies the code
d) it currently causes problems with memoization

David Blaikie b0b645cad1 Debug Info: Using declarations/DW_TAG_imported_declaration of variables, types, and functions.
Basic support is implemented here - it still doesn't account for
declared-but-not-defined variables or functions. It cannot handle out of
order (declared, 'using', then defined) cases for variables, but can
handle that for functions (& can handle declared, 'using'd, and not
defined at all cases for types).

David Blaikie 3b6038b6f3 Debug Info: Support DW_TAG_imported_declaration
This provides basic functionality for imported declarations. For
subprograms and types some amount of lazy construction is supported (so
the definition of a function can proceed the using declaration), but it
still doesn't handle declared-but-not-defined functions (since we don't
generally emit function declarations).

Variable support is really rudimentary at the moment - simply looking up
the existing definition with no support for out of order (declaration,
imported_module, then definition).

Jim Ingham 221d51cf84 Figure out the reply to "PlanExplainsStop" once when we stop and then use the cached
value.  This fixes problems, for instance, with the StepRange plans, where they know that
they explained the stop because they were at their "run to here" breakpoint, then deleted
that breakpoint, so when they got asked again, doh!  I had done this for a couple of plans
in an ad hoc fashion, this just formalizes it.

Also add a "ResumeRequested" in Process so that the code in the completion handlers can
tell the ShouldStop logic they want to resume rather than just directly resuming.  That allows 
us to handle resuming in a more controlled fashion.

Also, SetPublicState can take a "restarted" flag, so that it doesn't drop the run lock when
the target was immediately restarted.
