FoldingSetTrait instead of directly calling a 'Profile' method.

'FoldingSetNodeImpl' (previously 'FoldingSetNodeID' was a typedef of
'FoldingSetNodeImpl::NodeID').

Why?  Clients can now easily forward declare 'FoldingSetNodeID' without having
to include FoldingSet.h.

instead of always assuming that the stored objects had a method called
'Profile'. The default behavior is to dispatch to a 'Profile' method (as
before), but via template specialization this behavior can now be overridden by
clients.

Added templated class 'FoldingSetNodeWrapper', a generic wrapper class that
allows one to insert objects into a FoldingSet that do not directly inherit from
FoldingSetNode. This is useful for inserting objects that do not always need to
pay the overhead of inheriting from FoldingSetNode, or were designed with that
behavior in mind.

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.

_test:

instead of:

_test:

	stfd f0, -8(r1)

	nop
	lwz r2, -4(r1)
	stb r2, 0(r4)

The former is not correct (stores 4 bytes, not 1).

an iterator, since the implementation returned an iterator that pointed to a
different node! Renamed this implementation to SlimFind() so that users do not
expect it to return an iterator (it is a more efficient implementation than
returning an iterator if the user just wants to find the value of a key).

Added a FIXME to implement ImmutableMap::find() that returns an iterator.

this change tickled a latent bug in Darwin's strip,
so revert it for now as a workaround.

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.

Fixed CellSPU's A-form (local store) address mode, so that all globals,
externals, constant pool and jump table symbols are now wrapped within
a SPUISD::AFormAddr pseudo-instruction. This now identifies all local
store memory addresses, although it requires a bit of legerdemain during
instruction selection to properly select loads to and stores from local
store, properly generating "LQA" instructions.

Also added mul_ops.ll test harness for exercising integer multiplication.
