Predefine __NO_MATH_ERRNO__ for -fno-math-errno.

This patch adds a predefined macro __NO_MATH_ERRNO__ for when
-fno-math-errno is passed or implied.  This allows math.h to provide a
more accurate definition of the C99 math_errhandling macro that takes
this option into account, and allows for choice of libm functions to
be optimized at compile time based on this option.

(There may be a case for such interfaces for -fno-rounding-math
(default) and -fno-trapping-math as well, but as C99 standard pragmas
would allow those to vary on a per-block basis, predefined macros
would be problematic as the interface; you can't select a
-fno-trapping-math or -fno-rounding-math version of a function in a
standard header if a conforming program could then use "#pragma STDC
FENV_ACCESS ON" to require a -ftrapping-math -frounding-math version
in a particular block.  So built-in functions might be a better way of
providing access to information about those options.)

Bootstrapped with no regressions on x86_64-unknown-linux-gnu.  OK to
commit?

* cppbuiltin.c (define_builtin_macros_for_compilation_flags):

Error out for Cilk_spawn or array expression in forbidden places

_Cilk_spawn or Cilk array expressions are only allowed on their own,
but not in for(), if(), switch, do, while, goto, etc.
The C parser didn't always check for that, which lead to ICEs earlier
for invalid code.

Add a generic helper that checks this and call it where needed
in the C frontend.

I chose to allow spawn/array for for init and increment expressions.
While the Cilk spec could be interpreted to forbid it there too
there didn't seem any reason to not allow it.

One dark corner is spawn, array in statement expressions not at
the end. Right now that's forbidden too.
