In CFG dumper, refactored the code to print block terminators into a

detects blocks that start with labels and doesn't do a second reversal.

canonicalized queries of a variable's storage:
hasAutoStorage - Does a variable have (implicit) auto storage?

hasGlobalStorage - Is the variable a global variable or a static
local variable?
Additional comments documenting these functions are included in the

Added support for additional format string checking for the printf
...
family of functions. Previous functionality only included checking to
see if the format string was a string literal. Now we check parse the
format string (if it is a literal) and perform the following checks:
(1) Warn if: number conversions (e.g. "%d") != number data arguments.
(2) Warn about missing format strings (e.g., "printf()").
(3) Warn if the format string is not a string literal.
(4) Warn about the use se of '%n' conversion. This conversion is
discouraged for security reasons.
(5) Warn about malformed conversions. For example '%;', '%v'; these
are not valid.
(6) Warn about empty format strings; e.g. printf(""). Although these
can be optimized away by the compiler, they can be indicative of
broken programmer logic. We may need to add additional support to
see when such cases occur within macro expansion to avoid false
positives.
(7) Warn if the string literal is wide; e.g. L"%d".
(8) Warn if we detect a '\0' character WITHIN the format string.
Test cases are included.

Two typeof() related changes...
...
- Changed the name of ASTContext::getTypeOfType(Expr*)->getTypeOfExpr().
- Remove FIXME for TypeOfExpr::getAsStringInternal(). This will work fine for printing the AST. It isn't ideal
for error diagnostics (since it's more natural to display the expressions type).
One "random" (or at least delayed:-) change...
- Changed all "ext_typecheck_*" diagnostics from EXTENSION->WARNING. Reason: Since -pedantic is now
off (by default), these diagnostics were never being emitted (which is bad). With this change, clang will
emit the warning all the time. The only downside (wrt GCC compatibility) is -pedantic-errors will not turn
this diagnostics into errors (a "feature" of making tagging them with EXTENSION). When/if this becomes
an issue, we can revisit.

Implement pretty diagnostics when doing on-the-fly vector sizing (for vector component access).
...
For example, before this commit, the following diagnostics would be emitted...
ocu.c:49:12: error: incompatible types assigning 'float __attribute__((ocu_vector_type(3)))' to 'float4'
vec4_2 = vec4.rgb; // shorten
~~~~~~ ^ ~~~~~~~~
ocu.c:51:7: error: incompatible types assigning 'float __attribute__((ocu_vector_type(2)))' to 'float'
f = vec2.xx; // shorten
~ ^ ~~~~~~~
Now, the diagnostics look as you would expect...
ocu.c:49:12: error: incompatible types assigning 'float3' to 'float4'
vec4_2 = vec4.rgb; // shorten
~~~~~~ ^ ~~~~~~~~
ocu.c:51:7: error: incompatible types assigning 'float2' to 'float'
f = vec2.xx; // shorten
~ ^ ~~~~~~~
