[Parse] Allow 'constexpr' in condition declarations
This patch implements the functionality specified by DR948.
The changes are two fold. First, the parser was modified
to allow 'constexpr's to appear in condition declarations
(which was a hard error before). Second, Sema was modified
to cleanup maybe odr-used declarations by way of a call to
'ActOnFinishFullExpr'. As 'constexpr's were not allowed in
condition declarations before the cleanup wasn't necessary
(such declarations were always odr-used).

Resubmitting 240466 after fixing the linux test suite failures.
A few extras were fixed
- Symbol::GetAddress() now returns an Address object, not a reference. There were places where people were accessing the address of a symbol when the symbol's value wasn't an address symbol. On MacOSX, undefined symbols have a value zero and some places where using the symbol's address and getting an absolute address of zero (since an Address object with no section and an m_offset whose value isn't LLDB_INVALID_ADDRESS is considered an absolute address). So fixing this required some changes to make sure people were getting what they expected.
- Since some places want to access the address as a reference, I added a few new functions to symbol:
Address &Symbol::GetAddressRef();
const Address &Symbol::GetAddressRef() const;

Enable ISL's small integer optimization
Summary:
With small integer optimization (short: sio) enabled, ISL uses 32 bit
integers for its arithmetic and only falls back to a big integer library
(in the case of Polly: IMath) if an operation's result is too large.
This gives a massive performance boost for most application using ISL.
For instance, experiments with ppcg (polyhedral source-to-source
compiler) show speed-ups of 5.8 (compared to plain IMath), respectively
2.7 (compared to GMP).
In Polly, a smaller fraction of the total compile time is taken by ISL,
but the speed-ups are still very significant. The buildbots measure
compilation speed-up up to 1.8 (oourafft, floyd-warshall, symm). All
Polybench benchmarks compile in at least 9% less time, and about 20%
less on average.

[mips] [IAS] Fix parsing of memory offset expressions with parenthesis depth >1.
Summary:
In an expression such as "(((a+b)+c)+d)", parseParenExpression() would only parse the "a+b)+c", which would result in an error later on in the parser.
This means that we can only parse one level of inner parentheses.
In order to fix this, I added a new function called parseParenExprOfDepth(), which parses a specified number of trailing parenthesis expressions
(except for the outermost parenthesis), and changed MipsAsmParser to use it in parseMemOffset instead of parseParenExpression().

Note that __imp_hello is not defined anywhere.
void hello() { printf("Hello\n"); }
extern void (*__imp_hello)();
int main() { __imp_hello(); }
Function symbols exported from DLLs are automatically mangled by appending
__imp_ prefix, so they have two names (original one and with the prefix).
This "feature" seems to simulate that behavior even for non-DLL symbols.
This is in my opnion very odd feature. Even MSVC linker warns if you use this.
I'm adding that anyway for the sake of compatibiltiy.
