Also fix some comments.

Change it back again: destructors and constructors need to be run.

This fixes the MC/COFF/basic-coff.ll test case.

getMaxRegionExit returns the exit of the maximal refined region starting
at a specific basic block.

are still on the list.  This might happen if a CallbackVH created some new value
handles for the old value when doing RAUW.  Barf if it occurs, since it is almost
certainly a mistake.

subregister operands like this:

%reg1040:sub_32bit<def> = MOV32rm <fi#-2>, 1, %reg0, 0, %reg0, %reg1040<imp-def>; mem:LD4[FixedStack-2](align=8)

Make them return false when subreg operands are present. VirtRegRewriter is
making bad assumptions otherwise.

This fixes PR7713.

The next step is to warn if a block labeled unreachable is, in fact, reachable. Somewhat related to PR810.

protectors, to be near the stack protectors on the stack. Accomplish this by
tagging the stack object with a predicate that indicates that it would trigger
this. In the prolog-epilog inserter, assign these objects to the stack after the
stack protector but before the other objects.

Groundwork for C string length tracking. Currently only handles the length of constant string literals, which is not too helpful, and only calls to strlen() are checked.

A good start on ecma regex's.  Maybe even feature complete, not sure yet.  Also an unrelated fix to is_constructible thanks to Daniel Krugler.

Make sure these containters get cleared by clear(), which IndVarSimplify
and LSR both use before deleting instructions.

which doesn't work.  Turns out we don't need to
do anything for constants.
