e8e01b600c I forgot to update the prototype for LLVMBuildIntCast when correcting 
the body to not pass the name for the isSigned parameter.  However it
seems that changing prototypes is a big-no-no, so here I revert the
previous change and pass "true" for isSigned, meaning this always does
a signed cast, which was the previous behaviour assuming the name was
not NULL!  Some other C function needs to be introduced for the general
case of signed or unsigned casts.  This hopefully unbreaks the ocaml
binding.

ead2dacc9e FileCheck, PR5239: Try to find the intended match on failures, but looking for a 
good nearby fuzzy match. Frequently the input is nearly correct, and just
showing the user the a nearby sensible match is enough to diagnose the problem.
 - The "fuzzyness" is pretty simple and arbitrary, but worked on my three test
   cases. If you encounter problems, or places you think FileCheck should have
   guessed but didn't, please add test cases to PR5239.

For example, previously FileCheck would report this:
--
t.cpp:21:55: error: expected string not found in input
// CHECK: define void @_Z2f25f2_s1([[i64_i64_ty]] %a0)
                                                      ^
<stdin>:19:30: note: scanning from here
define void @_Z2f15f1_s1(%1) nounwind {
                             ^
<stdin>:19:30: note: with variable "i64_i64_ty" equal to "%0"
--

and now it also reports this:
--
<stdin>:27:1: note: possible intended match here
define void @_Z2f25f2_s1(%0) nounwind {
^
--

which makes it clear that the CHECK just has an extra ' %a0' in it, without
having to check the input.

a2f20b20a8 Add getFrameIndexReference() to TargetRegisterInfo, which allows targets to 
tell debug info which base register to use to reference a frame index on a
per-index basis. This is useful, for example, in the presence of dynamic
stack realignment when local variables are indexed via the stack pointer and
stack-based arguments via the frame pointer.

2214dc0764 Fix pr5470. Tablegen handles template arguments by temporarily setting their 
values, resolving references to them, and then removing the definitions.
If a template argument is set to an undefined value, we need to resolve
references to that argument to an explicit undefined value.  The current code
leaves the reference to the template argument as it is, which causes an
assertion failure later when the definition of the template argument is
removed.
