[analyzer] Introduce ObjCSelfInitChecker, which checks initialization methods to verify that they assign 'self' to the
result of an initialization call (e.g. [super init], or [self initWith..]) before using any instance variable or
returning 'self'.

the prefix should be ignored.

E.g. if ignorePrefix is true, "_init" and "init" selectors will both be result in InitRule, but if
ignorePrefix is false, only "init" will return InitRule.

McARM: Sketch some logic for determining when to add carry set and predication code operands based on the "canonical mnemonic".

carry setting flag from the mnemonic.

Note that this currently involves me disabling a number of working cases in
arm_instructions.s, this is a hopefully short term evil which will be rapidly
fixed (and greatly surpassed), assuming my current approach flies.

"this" pointer for any subclass of User, you could static_cast it to
User* and then reinterpret_cast that to Use* to get the end of the
operand list. This isn't a safe assumption in general, because the
static_cast might adjust the "this" pointer. Fixed by having these
OperandTraits classes take an extra template parameter, which is the
subclass of User. This is groundwork for PR889.

Factor the actual simplification out of SimplifyIndirectBrOnSelect and into a new helper function so it can be reused in e.g. an upcoming SimplifySwitchOnSelect.

In Microsoft mode, force 64 bit hex integer constants to signed type if the LL or i64 suffix is used. This MSVC behavior.

For example:

void f(long long){ printf("long long"); }
void f(unsigned long long) { printf("unsigned long long"); }
int main() {
   f(0xffffffffffffffffLL);
}
Will print "long long" using MSVC.

This patch also fixes 16 compile errors related to overloading issues when parsing the MSVC 2008 C++ standard lib.

llvm-svn: 123231

i64 is like LL
i32 is like L

Also set isMicrosoftInteger to true only if the suffix is well formed.

Filling no-ops is done just before emitting of assembly,
when the instruction stream is final. No-ops are inserted
to align the instructions so the dual-issue of the pipeline
is utilized. This speeds up generated code with a minimum of 
1% on a select set of algorithms.

This pass may be redundant if the instruction scheduler and 
all subsequent passes that modify the instruction stream 
(prolog+epilog inserter, register scavenger, are there others?)
are made aware of the instruction alignments.

I'm skeptical that this is the actual problem behind PR8954, but
this is a stab in the right direction.
