3d73bce2d0 don't hoist FP additions into unconditional adds + selects. This
could theoretically introduce a trap, but is also a performance issue.
This speeds up ptrdist/ks by 8%.

227ff79ceb An example for which the TYPE_SIZE was being set from
the initial value, while the type fields were not (this
is a qualified union type, so not all fields are always
present).  This resulted in the size of the corresponding
LLVM type being larger than the gcc TYPE_SIZE.

0e13821c96 GC poses hazards to the inliner. Consider:
define void @f() {
            ...
            call i32 @g()
            ...
    }

    define void @g() {
            ...
    }

The hazards are:

  - @f and @g have GC, but they differ GC. Inlining is invalid. This
    may never occur.
  - @f has no GC, but @g does. g's GC must be propagated to @f.

The other scenarios are safe:

  - @f and @g have the same GC.
  - @f and @g have no GC.
  - @g has no GC.

This patch adds inliner checks for the former two scenarios.

d9d70395d9 Get the verifier to check attributes on calls as well
as on functions.  Make it verify invokes and not just
ordinary calls.  As a (desired) side-effect, it is no
longer legal to have call attributes on arguments that
are being passed to the varargs part of a varargs
function (llvm-as drops them on the floor anyway).

110c835039 Make DAE not wipe out attributes on calls, and not drop
return attributes on the floor.  In the case of a call
to a varargs function where the varargs arguments are
being removed, any call attributes on those arguments
need to be dropped.  I didn't do this because I plan to
make it illegal to have such attributes (see next patch).
With this change, compiling the gcc filter2 eh test at -O0
and then running opt -std-compile-opts on it results in
a correctly working program (compiling at -O1 or higher
results in the test failing due to a problem with how we
output eh info into the IR).
