Peter Collingbourne c377275a4a DataFlowSanitizer; Clang changes.
DataFlowSanitizer is a generalised dynamic data flow analysis.

Unlike other Sanitizer tools, this tool is not designed to detect a
specific class of bugs on its own.  Instead, it provides a generic
dynamic data flow analysis framework to be used by clients to help
detect application-specific issues within their own code.

Daniel Malea d79ae05080 New settings: target.use-hex-immediates and target.hex-immediates-style
- Immediates can be shown as hex (either Intel or MASM style)
- See TestSettings.py for usage examples
- Verified to cause no regressions on Linux x86_64 (Ubuntu 12.10)

Argyrios Kyrtzidis acfbbd77f8 [PCH] Fix a PCH serialization crash, with invalid code related to forward enum references.
The problem was that an enum without closing semicolon could be associated as a forward enum
in an erroneous declaration, leading to the identifier being associated with the enum decl but
without a declaration actually referencing it.
This resulted in not having it serialized before serializing the identifier that is associated with.

Also prevent the ASTUnit from querying the serialized DeclID for an invalid top-level decl; it may not
have been serialized.

Reid Kleckner 11da004ac1 On Windows, autolink advapi32 from Path.inc for CryptAcquireContextW
This allows llvm-tblgen to link successfully when compiling with clang.

Both MSBuild and CMake will automatically add advapi32 as part of a set
of other dlls comprising the win32 API to the link line, but CMake
doesn't do that when compiling with clang.  Until someone adds that info
to cmake upstream, this seems like a reasonable work around.

Manuel Klimek a027f306a6 Fixes a couple of bugs with the Allman brace breaking.
In particular, left braces after an enum declaration now occur on their
own line.  Further, when short ifs/whiles are allowed these no longer
cause the left brace to be on the same line as the if/while when a
brace is included.

at the element type when getLargeArrayMinWidth returned non zero.

Jordan Rose 54533f73a8 Eliminate CXXConstructorDecl::IsImplicitlyDefined.
This field is just IsDefaulted && !IsDeleted; in all places it's used,
a simple check for isDefaulted() is superior anyway, and we were forgetting
to set it in a few cases.

Also eliminate CXXDestructorDecl::IsImplicitlyDefined, for the same reasons.

No intended functionality change.

Alexander Potapenko ce32410097 [TSan] Let the users suppress use-after-free errors using the "race:" suppressions.
If there's a race between a memory access and a free() call in the client program,
it can be reported as a use-after-free (if the access occurs after the free()) or an ordinary race
(if free() occurs after the access).
We've decided to use a single "race:" prefix for both cases instead of introducing a "use-after-free:" one,
because in many cases this allows us to keep a single suppression for both the use-after-free and free-after-use.

This may be misleading if the use-after-free occurs in a non-racy way (e.g. in a single-threaded program).
But normally such bugs shall not be suppressed.

Richard Sandiford 0897fce2f4 [SystemZ] Optimize floating-point comparisons with zero
This follows the same lines as the integer code.  In the end it seemed
easier to have a second 4-bit mask in TSFlags to specify the compare-like
CC values.  That eats one more TSFlags bit than adding a CCHasUnordered
would have done, but it feels more concise.

Benjamin Kramer 6a4976d3e0 JumpThreading: Turn a select instruction into branching if it allows to thread one half of the select.
This is a common pattern coming out of simplifycfg generating gross code.

a:                                       ; preds = %entry
  %sel = select i1 %cmp1, double %add, double 0.000000e+00
  br label %b

b:
  %cond5 = phi double [ %sel, %a ], [ %sub, %entry ]
  %cmp6 = fcmp oeq double %cond5, 0.000000e+00
  br i1 %cmp6, label %if.then, label %if.end

becomes

a:
  br i1 %cmp1, label %b, label %if.then

b:
  %cond5 = phi double [ %sub, %entry ], [ %add, %a ]
  %cmp6 = fcmp oeq double %cond5, 0.000000e+00
  br i1 %cmp6, label %if.then, label %if.end

Skipping block b completely if possible.

r187874 seems to have been missed by the build bot infrastructure, and
