is not profitable in many cases
because moden processos can store multiple values in parallel, and preparing the consecutive store requires
some work. We only handle these cases:
1. Consecutive stores where the values and consecutive loads. For example:
int a = p->a;
int b = p->b;
q->a = a;
q->b = b;
2. Consecutive stores where the values are constants. Foe example:
q->a = 4;
q->b = 5;

buildbots. Original commit message:
A DAGCombine optimization for merging consecutive stores. This optimization is not profitable in many cases
because moden processos can store multiple values in parallel, and preparing the consecutive store requires
some work. We only handle these cases:
1. Consecutive stores where the values and consecutive loads. For example:
int a = p->a;
int b = p->b;
q->a = a;
q->b = b;
2. Consecutive stores where the values are constants. Foe example:
q->a = 4;
q->b = 5;

bug fixes, and with improved heuristics for analyzing foreign-loop
addrecs.
This change also flattens IVUsers, eliminating the stride-oriented
groupings, which makes it easier to work with.

loops when they can be subsumed into addressing modes.
Change X86 addressing mode check to realize that
some PIC references need an extra register.
(I believe this is correct for Linux, if not, I'm sure
someone will tell me.)

Update the test suite to accommodate the change from signed integer types
to signless integer types. The changes were of only a few kinds:
1. Make sure llvm-upgrade is run on the source which does the bulk of the
changes automatically.
2. Change things like "grep 'int'" to "grep 'i32'"
3. In several tests bitcasting caused the same name to be reused in the
same type plane. These had to be manually fixed. The fix was (generally)
to leave the bitcast and provide the instruction with a new name. This
should not affect the semantics of the test. In a few cases, the
bitcasts were known to be superfluous and irrelevant to the test case
so they were removed.
4. One test case uses a bytecode file which needed to be updated to the
latest bytecode format.
