Speed up the predicate used to decide when to inline by caching the size
...
of callees between executions.
On eon, in release mode, this changes the inliner from taking 11.5712s
to taking 2.2066s. In debug mode, it went from taking 14.4148s to
taking 7.0745s. In release mode, this is a 24.7% speedup of gccas, in
debug mode, it's a total speedup of 11.7%.
This also makes it slightly more aggressive. This could be because we
are not judging the size of the functions quite as accurately as before.
When we start looking at the performance of the generated code, this can
be investigated further.

This changes the PromoteMemToReg function to create "pruned" SSA form, not
...
"minimal" SSA form (in other words, it doesn't insert dead PHIs). This
speeds up the mem2reg pass very significantly because it doesn't have to
do a lot of frivolous work in many common cases.
In the 252.eon function I have been playing with, this doesn't even insert
the 120 PHI nodes that it used to which were trivially dead (in the process
of promoting 356 alloca instructions overall). This speeds up the mem2reg
pass from 1.2459s to 0.1284s. More significantly, the DCE pass used to take
2.4138s to remove the 120 dead PHI nodes that mem2reg constructed, now it
takes 0.0134s (which is the time to scan the function and decide that there
is nothing dead). So overall, on this one function, we speed things up a
total of 3.5179s, which is a 24.8x speedup! :)
This change is tested by the Mem2Reg/2003-10-05-DeadPHIInsertion.ll test,
which now passes.

Speed up the mem2reg transform for allocas which are only read/written in a single
...
basic block. This is amazingly common in code generated by the C/C++ front-ends.
This change makes it not have to insert ANY phi nodes, whereas before it would insert
a ton of dead ones which DCE would have to clean up.
Thus, this fix improves compile-time performance of these trivial allocas in two ways:
1. It doesn't have to do the walking and book-keeping for renaming
2. It does not insert dead phi nodes for them which would have to
subsequently be cleaned up.
On my favorite testcase from 252.eon, this special case handles 305 out of
356 promoted allocas in the function. It speeds up the mem2reg pass from 7.5256s
to 1.2505s. It inserts 677 fewer dead PHI nodes, which speeds up a subsequent
-dce pass from 18.7524s to 2.4806s.
There are still 120 trivially dead PHI nodes being inserted for variables used
in multiple basic blocks, but they are not handled by this patch.

*** Revamp the code which handled unreachable code in the function. Now the
code is much more efficient for high-degree basic blocks, such as those
that occur in the 252.eon SPEC benchmark.
For the interested, the time to promote a SINGLE alloca in _ZN7mrScene4ReadERSi
function used to be > 3.5s. Now it is < .075s. The function has a LOT of
allocas in it, so it appeared to be infinite looping, this should make it much
nicer. :)

This is effectively a complete rewrite of the globaldce algorithm, resulting
...
in it being both shorter and more effective. It no longer depends on the
callgraph, so one FIXME has been fixed.
Additionally, this pass was not able to delete recursive (but dead) functions
if they were pointed to by global variables which were also dead. In fact
this pass had a lot of problems deleting functions which were only pointed
to by dead globals and other stuff.
Fixing this means that the entire EH library should be stripped away now from
programs that don't use sjlj or exceptions.

Allow folding several instructions into casts, which can simplify a lot
...
of codes. For example,
short kernel (short t1) {
t1 >>= 8; t1 <<= 8;
return t1;
}
became:
short %kernel(short %t1.1) {
%tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1]
%tmp.5 = cast short %tmp.3 to int ; <int> [#uses=1]
%tmp.7 = shl int %tmp.5, ubyte 8 ; <int> [#uses=1]
%tmp.8 = cast int %tmp.7 to short ; <short> [#uses=1]
ret short %tmp.8
}
before, now it becomes:
short %kernel(short %t1.1) {
%tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1]
%tmp.8 = shl short %tmp.3, ubyte 8 ; <short> [#uses=1]
ret short %tmp.8
}
which will become:
short %kernel(short %t1.1) {
%tmp.3 = and short %t1.1, 0xFF00
ret short %tmp.3
}
This implements cast-set.ll:test4 and test5

Trace loads and stores as they happen (stores were being

Initial checkin of PRE on LLVM. This implementation is still lacking in

several ways:

FunctionResolve/2002-08-19-ResolveGlobalVars.ll because replaceAllUsesWith
breaks when a constantexpr is pointing to the thing being replaced. This
