Fix a nasty bug that caused us to unroll EXTREMELY large loops due to overflow
in the size calculation.
This is not something you want to see:
Loop Unroll: F[main] Loop %no_exit Loop Size = 2 Trip Count =
2147483648 - UNROLLING!
The problem was that 2*
2147483648 == 0.
Now we get:
Loop Unroll: F[main] Loop %no_exit Loop Size = 2 Trip Count =
2147483648 - TOO LARGE:
4294967296>100
Thanks to some anonymous person playing with the demo page that repeatedly
caused zion to go into swapping land. That's one way to ensure you'll get
a quick bugfix. :)

Second half of my fixed-sized-alloca patch. This folds the LEA to compute
the alloca address into common operations like loads/stores.
In a simple testcase like this (which is just designed to excersize the
alloca A, nothing more):
int %test(int %X, bool %C) {
%A = alloca int
store int %X, int* %A
store int* %A, int** %G
br bool %C, label %T, label %F
T:
call int %test(int 1, bool false)
%V = load int* %A
ret int %V
F:
call int %test(int 123, bool true)
%V2 = load int* %A
ret int %V2

Substantially improve code generation for address exposed locals (aka fixed
sized allocas in the entry block). Instead of generating code like this:
entry:
reg1024 = ESP+1234
... (much later)
*reg1024 = 17
Generate code that looks like this:
entry:
(no code generated)
... (much later)
t = ESP+1234
*t = 17
The advantage being that we DRAMATICALLY reduce the register pressure for these
silly temporaries (they were all being spilled to the stack, resulting in very
silly code). This is actually a manual implementation of rematerialization :)
I have a patch to fold the alloca address computation into loads & stores, which
will make this much better still, but just getting this right took way too much time
and I'm sleepy.
