for register tokens. Before, if it encountered
'%al,' it would report 'al,' as the token. Now it
correctly reports '%al'.

cast needs to adjust for a vtable pointer when going from base to
derived type (when the base doesn't have a vtable but the
derived type does).

The 'R' suffix means the to-integer operations use the rounding mode specified
by the FPSCR, encoded as Inst{7} = 0.

in global initializers. Instead of aborting, attempt to fold them on the
spot. If folding succeeds, emit the folded expression instead.
This fixes PR6255.

we can get in here if FastISel gives up in a block.
(Actually the two copies of this need to be unified. Later.)

Use a temp dir with a unique name in the current dir itself.
Use forward_value instead of unpack_values.

warns about this base class not having a virtual destructor, but since
this class has no virtual methods and neither it or the types derived
from it has a destructor, a protected trivial destructor will do (and
shuts cppcheck up) the trick without the cost of introducing a vtable.

if its type (but respect the alignment).
- Store all variable arguments back to the caller stack.

only run for x86 with fastisel. I've found it being very effective in
eliminating some obvious dead code as result of formal parameter lowering
especially when tail call optimization eliminated the need for some of the loads
from fixed frame objects. It also shrinks a number of the tests. A couple of
tests no longer make sense and are now eliminated.

This time it's for real! I am going to hook this up in the frontends as well.
The inliner has some experimental heuristics for dealing with the inline hint.
When given a -respect-inlinehint option, functions marked with the inline
keyword are given a threshold just above the default for -O3.
We need some experiments to determine if that is the right thing to do.
