216bcceee1 Special handling of __builtin_expect in boolean expressions
...as found in Mac OS X' assert macro definition,

  __builtin_expect(!(e), 0) ? ... : ...

with type

  long __builtin_expect(long, long)

The code in literaltoboolconversion.cxx is needed for

  assert(false);

b21e3d16aa Clang API function terminology got changed
...at least in trunk 200400 towards Clang 3.5.

1f078fcadd Prepare dual-mode compiler plugin feature
...which can act as either a rewriter or a non-rewriter that emits warnings.

Also added COMPILER_PLUGIN_WARNINGS_ONLY=X to demote warnings from plugin X from
errors to warnings, even under --enable-werror.

cd20baf40a implicitboolconversion: warn about mixing bool with integer
...in &=, |=, ^=, as does MSVC, too.

8128644312 implicitboolconversion: also warn about mixing bool/sal_Bool in &=, |=, ^=
...as MSVC would warn about those anyway.

cb710f3a1e implicitboolconversion: also warn about mixing bool/sal_Bool in == etc.
...as MSVC would warn about those anyway (at least about cases that do not
compare against literal sal_True/sal_False, but warning even about those helped
clean up lots of redundant

  if (foo == true)

instead of just

  if (foo)

etc. across the code base).

e908f69ec0 Clang plugin that flags implicit conversions from bool
...as they are often enough errors, like a typo in brace placement in

  if (foo == (FOO || bar == BAR) && baz)

or a literal true passed as an argument to a function that rather expects an
integer bit mask, etc.  The plugin is smart enough to detect interaction with
logically boolean return/parameter types of C functions that use [unsigned] int
instead, and knows the relevant boolean typedefs (sal_Bool, gboolean, etc.).
