if/switch/while/do/for statements. Previously, we would end up either:

  (1) Forgetting to destroy temporaries created in the condition (!),
  (2) Destroying the temporaries created in the condition *before*
  converting the condition to a boolean value (or, in the case of a
  switch statement, to an integral or enumeral value), or
  (3) In a for statement, destroying the condition's temporaries at
  the end of the increment expression (!).

We now destroy temporaries in conditions at the right times. This
required some tweaking of the Parse/Sema interaction, since the parser
was building full expressions too early in many places.

Fixes PR7067.

handled cases where a block had zero predecessors, but failed to detect other
cases like loops with no entries.  The SSAUpdater is already doing a forward
traversal through the blocks, so it is not hard to identify the blocks that
were never reached on that traversal.  This fixes the crash for ppc on the
stepanov_vector test.

inlineable.  That header file has to be TypeLoc.h, which means that
TypeLoc.h needs to depend on Decl.h because TypeSourceInfo doesn't
have its own header.  That could be remedied, though.

"bottom-up" when implicit casts and comparisons are inserted, compute them
"top-down" when the full expression is finished.  Makes it easier to
coordinate warnings and thus implement -Wconversion for signedness
conversions without double-warning with -Wsign-compare.  Also makes it possible
to realize that a signedness conversion is okay because the context is
performing the inverse conversion.  Also simplifies some logic that was
trying to calculate the ultimate comparison/result type and getting it wrong.
Also fixes a problem with the C++ explicit casts which are often "implemented"
in the AST with a series of implicit cast expressions.

Re-apply 103156 and 103157. 103156 didn't break anything. 10315 exposed a coalescer bug that's fixed by 103170.

%reg1039:1<def> = VMOVS %S1<kill>, pred:14, pred:%reg0
is not coalescable since none of the super-registers of S1 are in reg1039's
register class: DPR_VFP2. But it is still a legal copy instruction so it should
not assert.
