reasoning about OSCompareAndSwap32Barrier/OSCompareAndSwap64Barrier. Essentially
the address of reference to a region (pointer-to-pointer) can be casted to
(int32_t*), and we need to handle the logic to convert the involved locations
back and forth from nonloc::LocAsInteger, nonloc::ConcreteInt, to Loc and
loc::ConcreteInt respectively. This adds some potentially suspect logic to
BasicStoreManager that allows the analyzer to reason about abuses of the C type
system. This should probably be refined, be ported over to RegionStoreManager,
and extended with "path-sensitive type checking" to flag bugs in clearly
incoherent code.

1. In a struct field redefinition, don't mark the struct erroneous.  The
   field is erroneous, but the struct is otherwise well formed.
2. Don't emit diagnostics about functions that are known to be broken already.

Either fix is sufficient to silence the second diagnostic in the example,
but the combination is better :)

the extra argument warnings, and -Wformat -Wno-format-extra-args
turns on -Wformat but not the extra-args warnings.

llvm-svn: 70363

1. All all variants of -Wformat*, make them imply -Wformat.  GCC warns 
   if you use -Wformatfoo without -Wformat.  We just make one imply the 
   other.
2. Make -Wformat-nonliteral default to off, like gcc.  It is an incredible
   nuisance.
3. Accept but currently ignore -Wformat-extra-args.

anything larger than 64-bits, avoiding a crash.  This should
really be fixed to use APInts, though type legalization happens
to help us out and we get good code on the attached testcase at
least.

an optimization level instead of a simple boolean telling it to generate code
"fast" or the other type of "fast".

llvm-svn: 70347

Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
use the old behavior, the flag is -O0. This change allows for finer-grained
control over which optimizations are run at different -O levels.

Most of this work was pretty mechanical. The majority of the fixes came from
verifying that a "fast" variable wasn't used anymore. The JIT still uses a
"Fast" flag. I'll change the JIT with a follow-up patch.
