9455a61009 InlineCost: Make TotalAllocaSizeRecursiveCaller unsigned to avoid sign-compare warnings. 
It's a size, not a cost.

c4ba62ca1d Move load_to_switch.ll to test/CodeGen/SPARC/ 
Because the test invokes llc -march=sparc, it needs to be in a directory
which is only run when the sparc target is built.

92df026f0d Prevent inlining of callees which allocate lots of memory into a recursive caller. 
Example:

void foo() {
 ... foo();   // I'm recursive!

  bar();
}

bar() {  int a[1000];  // large stack size }

93ba133906 CodeGenPrep: turn lookup tables into switches for some targets. 
This is a follow-up from r163302, which added a transformation to
SimplifyCFG that turns some switches into loads from lookup tables.

It was pointed out that some targets, such as GPUs and deeply embedded
targets, might not find this appropriate, but SimplifyCFG doesn't have
enough information about the target to decide this.

This patch adds the reverse transformation to CodeGenPrep: it turns
loads from lookup tables back into switches for targets where we do not
build jump tables (assuming these are also the targets where lookup
tables are inappropriate).

Hopefully we will eventually get to have target information in
SimplifyCFG, and then this CodeGenPrep transformation can be removed.

67076a91cf Silence -Wnon-virtual-dtor in llvm-stress. 
This was making it hard to scan my builds for new warnings. The
warning still fires with ToT clang. But if my workaround is unnecessary
for whatever reason, feel free to revert.

57838db0a1 De-nest if's and fix mix-up 
Two deeply nested if's obscured that the sense of the conditions was
mixed up. Amazingly, TableGen's output is exactly the same even with the
sense of the tests fixed; it seems that all of TableGen's conversions
are symmetric so that the inverted sense was nonetheless correct "by
accident". As such, I couldn't come up with a test case.

If there does in fact exist a non-symmetric conversion in TableGen's
type system, then a test case should be prepared.

Despite the symmetry, both if's are left in place for robustness in the
face of future changes.

38f35fd3b7 Fix the last crasher I've gotten a reproduction for in SROA. This one 
from the dragonegg build bots when we turned on the full version of the
pass. Included a much reduced test case for this pesky bug, despite
bugpoint's uncooperative behavior.

Also, I audited all the similar code I could find and didn't spot any
other cases where this mistake cropped up.

7c8df7aa0c Fix getCommonType in a different way from the way I fixed it when 
working on FCA splitting. Instead of refusing to form a common type when
there are uses of a subsection of the alloca as well as a use of the
entire alloca, just skip the subsection uses and continue looking for
a whole-alloca use with a type that we can use.

This produces slightly prettier IR I think, and also fixes the other
failure in the test.
