Fix rdar://6719156 - clang should emit a better error when blocks are disabled but are used anyway
...
by changing blocks from being disabled in the parser to being disabled
in Sema.

Fix a long standard problem with clang retaining "too much" sugar
...
information about types. We often print diagnostics where we say
"foo_t" is bad, but the user doesn't know how foo_t is declared
(because it is a typedef). Fix this by expanding sugar when present
in a diagnostic (and not one of a few special cases, like vectors).
Before:
t.m:5:2: error: invalid operands to binary expression ('typeof(P)' and 'typeof(F)')
MAX(P, F);
^~~~~~~~~
t.m:1:78: note: instantiated from:
#define MAX(A,B) ({ __typeof__(A) __a = (A); __typeof__(B) __b = (B); __a < __b ? __b : __a; })
^
After:
t.m:5:2: error: invalid operands to binary expression ('typeof(P)' (aka 'struct mystruct') and 'typeof(F)' (aka 'float'))
MAX(P, F);
^~~~~~~~~
t.m:1:78: note: instantiated from:
#define MAX(A,B) ({ __typeof__(A) __a = (A); __typeof__(B) __b = (B); __a < __b ? __b : __a; })
^

just silently return an error to avoid bogus diagnostics.
