Fix two bugs with an @throw that doesn't have a statement.
- ObjCAtThrowStmt::getSourceRange() needs to check if it has a statement (and not go "boom":-)
- RewriteTest::RewriteObjCThrowStmt() needs to generate refer to the current exception.

Sema::FinalizeDeclaratorGroup(): Tighten up the tentative definition rule when dealing with arrays.

Bug submitted by Eli.

llvm-svn: 46179

Assert that the type of the cast is equal to the _unqualified_ type of the subexpression. Fixes a problem spotted by Nuno Lopes.

Added pruning of dead block-level expressions and Decls from our value map
using liveness information.

the RHS of the assignment.

the position *before* a statement, regardless of whether we are doing a

is because GNU-style Statement-expressions cause the last statement in the
statement-expression to act like an expression.

We now have two notions: block-level statements and block-level expressions.

The former are all Stmt* that appear in the list of statements in CFGBlocks. The
latter is the subset of the former; these block-level statements are used as
subexpressions somewhere in the AST. CFG::isBlockExpr() returns true for the
latter, not the former (previously isBlockExpr() always returned true for
non-Expr Stmt*).

Modified the LiveVariables analysis to also track liveness state for block-level
expressions (using the updated definition of block-level expressions).

Modified the dataflow solver so that when it records values for block-level
statements, it records the dataflow value *before* the transfer function for a
Stmt* is evaluated (not after). This is more in sync in what clients will want.

Modified CFGStmtVisitor to record the current block-level statement.

values for the block-level expressions.

Modified 'LiveVariables' to provide the option to clients to record
liveness information for block-level expressions (using the above feature).

Modified 'DeadStores' to conform to the new interface of 'LiveVariables'.

Modified 'GRConstants' to compute liveness information for block-level
expressions.

__builtin_overload takes 2 or more arguments:
0) a non-zero constant-expr for the number of arguments the overloaded 
   functions will take
1) the arguments to pass to the matching overloaded function
2) a list of functions to match.

The return type of __builtin_overload is inferred from the function whose args
match the types of the arguments passed to the builtin.  For example:

float a;
float sinf(float);
int   sini(int);

float b = __builtin_overload(1, a, sini, sinf);

Says that we are overloading functions that take one argument, and trying to 
pass an argument of the same type as 'a'.  sini() does not match since it takes
and argument of type int.  sinf does match, so at codegen time this will turn
into float b = sinf(a);

Refactored the use of this method into both the Sema module and Analysis module,
which were using their own static functions that did the same thing.
