Paul Robinson 0334a047df Driver part of debugger tuning.
Adds driver options named -glldb and -gsce to mean -g plus tuning for
lldb and SCE debuggers respectively; the existing -ggdb option does
the same for gdb. Existing options -ggdb0, -ggdb1 etc. unpack into
-ggdb -g<N>.  (There will not be -glldb<N> or -gsce<N> options.) The
tuning gets a target-specific default in the driver, and is passed
into cc1 with the new -debugger-tuning option.

As fallout, fixes where '-gsplit-dwarf -g0' would ignore the -g0 part
on Linux.

Evgeniy Stepanov fd6f92d5cb Cross-DSO control flow integrity (Clang part).
Clang-side cross-DSO CFI.

* Adds a command line flag -f[no-]sanitize-cfi-cross-dso.
* Links a runtime library when enabled.
* Emits __cfi_slowpath calls is bitset test fails.
* Emits extra hash-based bitsets for external CFI checks.
* Sets a module flag to enable __cfi_check generation during LTO.

This mode does not yet support diagnostics.

Nico Weber c80367417c [clang-cl] Let /W4 map to -Wall -Wextra instead of just -Wall.
There's no way to make a flag alias to two flags, so add a /WCL4 flag that
maps to the All, Extra diag groups.  Fixes PR25563.

Artem Dergachev 733e71b73b [analyzer] Fix symbolic element index lifetime.
SymbolReaper was destroying the symbol too early when it was referenced only
from an index SVal of a live ElementRegion.

In order to test certain aspects of this patch, extend the debug.ExprInspection
checker to allow testing SymbolReaper in a direct manner.

Daniel Jasper 6501f7e8fd clang-format: Add an additional value to AlignAfterOpenBracket: AlwaysBreak.
Summary:
If this option is set, clang-format will always insert a line wrap, e.g.
before the first parameter of a function call unless all parameters fit
on the same line. This obviates the need to make a decision on the
alignment itself.

Use this style for Google's JavaScript style and add some minor tweaks
to correctly handle nested blocks etc. with it. Don't use this option
for for/while loops.

-assume-filename, -fallback-style, and -sort-includes are new.  (They're also

Daniel Jasper c1bc38ed4f clang-format: Add a new brace style "custom" as well as flags to

All presets have been chose to keep the existing formatting, so there
shouldn't be any difference in formatting behavior.

Also change the dump_format_style.py to properly document the nested
structs that are used to keep these flags discoverable among all the
configuration flags.
