David Majnemer 597293981d [MSVC] Turn C++ EH on my default

Ehsan Akhgari d851833c9a [MSVC Compat] Only warn for unknown clang-cl arguments
Summary:
MSVC's driver accepts all unknown arguments but warns about them.  clang
by default rejects all unknown arguments.  This causes issues
specifically with build systems such as autoconf which liberally pass
things such as $LDFLAGS to the compiler and expect everything to work.
This patch teaches clang-cl to ignore unknown driver arguments.

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.

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.

Daniel Jasper c1bc38ed4f clang-format: Add a new brace style "custom" as well as flags to
control the individual braces. The existing choices for brace wrapping
are now merely presets for the different flags that get expanded upon
calling the reformat function.

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.

Aaron Ballman 512fb64765 Rename AST node matchers to match the AST node names directly. Part of this rename also splits recordDecl() (which used to match CXXRecordDecl) into recordDecl() (that matches RecordDecl) and cxxRecordDecl (that matches CXXRecordDecl). Also adds isStruct(), isUnion(), and isClass() narrowing matchers for RecordDecl objects.

Aaron Ballman b85be665b0 Fixed HasDeclarationMatcher to properly convert all types into decls where possible. Added objcObjectPointerType(), objcInterfaceDecl(), templateTypeParmType(), injectedClassNameType(), and unresolvedUsingTypenameDecl(). Updated documentation for pointerType() to call out that it does not match ObjCObjectPointerType types. Changed pointsTo() to handle ObjCObjectPointerType as well as PointerType.
While this may seem like a lot of unrelated changes, they all relate back to fixing HasDeclarationMatcher.

This now allows us to write a matcher like:

varDecl(hasType(namedDecl(hasName("Foo"))))

that matches code using typedefs, objc interfaces, template type parameters, injected class names, or unresolved using typenames.

This flag causes the compiler to emit bit set entries for functions as well
as runtime bitset checks at indirect call sites. Depends on the new function
bitset mechanism.

Sanjay Patel a24296b459 add __builtin_unpredictable and convert to metadata
This patch depends on r246688 (D12341).

The goal is to make LLVM generate different code for these functions for a target that
has cheap branches (see PR23827 for more details):

int foo();

int normal(int x, int y, int z) {
   if (x != 0 && y != 0) return foo();
   return 1;
}

int crazy(int x, int y) {
   if (__builtin_unpredictable(x != 0 && y != 0)) return foo();
   return 1;
}
