indvars: Prototyping Sign/ZeroExtend elimination without canonical IVs.
...
No functionality enabled by default. Use -disable-iv-rewrite.
Extended IVUsers to keep track of the phi that represents the users' IV.
Added the WidenIV transform to replace a narrow IV with a wide IV
by doing a one-for-one replacement of IV users instead of expanding the
SCEV expressions. [sz]exts are removed and truncs are inserted.

This fixes one divergence between LLVM and binutils for ARM in the
...
text section.
Assume the following bit of annotated assembly:
.section .data.rel.ro,"aw",%progbits
.align 2
.LAlpha:
.long startval(GOTOFF)
.text
.align 2
.type main,%function
.align 4
main: ;;; assume "main" starts at offset 0x20
0x0 push {r11, lr}
0x4 movw r0, :lower16:(.LAlpha-(.LBeta+8))
;;; ==> (.AddrOf(.LAlpha) - ((.AddrOf(.LBeta) - .AddrOf(".")) + 8)
;;; ==> (??? - ((16-4) + 8) = -20
0x8 movt r0, :upper16:(.LAlpha-(.LBeta+8))
;;; ==> (.AddrOf(.LAlpha) - ((.AddrOf(.LBeta) - .AddrOf(".")) + 8)
;;; ==> (??? - ((16-8) + 8) = -16
0xc ... blah
.LBeta:
0x10 add r0, pc, r0
0x14 ... blah
.LGamma:
0x18 add r1, pc, r1
Above snippet results in the following relocs in the .o file for the
first pair of movw/movt instructions
00000024 R_ARM_MOVW_PREL_NC .LAlpha
00000028 R_ARM_MOVT_PREL .LAlpha
And the encoded instructions in the .o file for main: must be
00000020 <main>:
20: e92d4800 push {fp, lr}
24: e30f0fec movw r0, #65516 ; 0xffec i.e. -20
28: e34f0ff0 movt r0, #65520 ; 0xfff0 i.e. -16
However, llc (prior to this commit) generates the following sequence
00000020 <main>:
20: e92d4800 push {fp, lr}
24: e30f0fec movw r0, #65516 ; 0xffec - i.e. -20
28: e34f0fff movt r0, #65535 ; 0xffff - i.e. -1
What has to happen in the ArmAsmBackend is that if the relocation is PC
relative, the 16 bits encoded as part of movw and movt must be both addends,
not addresses. It makes sense to encode addresses by right shifting the value
by 16, but the result is incorrect for PIC.
i.e., the right shift by 16 for movt is ONLY valid for the NON-PCRel case.
This change agrees with what GNU as does, and makes the PIC code run.
MC/ARM/elf-movt.s covers this case.

Add some more Win64 EH directives:
...
- StartChained and EndChained delimit a chained unwind area, which can contain
additional operations to be undone if an exception occurs inside of it.
- UnwindOnly declares that this function doesn't handle any exceptions. If it
has a handler, it's an unwind handler instead of an exception handler.
- Lsda declares the location and size of the LSDA, which in the Win64 EH
scheme is kept inside the UNWIND_INFO struct. Windows itself ignores the
LSDA; it's used by the Language-Specific Handler (the "Personality Function"
from DWARF).

Now that SrcBits and DestBits always represent the primitive size, rather
...
than either the primitive size or the element primitive size (in the case
of vectors), simplify the vector logic. No functionality change. There
is some distracting churn in the patch because I lined up comments better
while there - sorry about that.

Tighten up checking of the validity of casts. (1) The IR parser would
...
happily accept things like "sext <2 x i32> to <999 x i64>". It would
also accept "sext <2 x i32> to i64", though the verifier would catch
that later. Fixed by having castIsValid check that vector lengths match
except when doing a bitcast. (2) When creating a cast instruction, check
that the cast is valid (this was already done when creating constexpr
casts). While there, replace getScalarSizeInBits (used to allow more
vector casts) with getPrimitiveSizeInBits in getCastOpcode and isCastable
since vector to vector casts are now handled explicitly by passing to the
element types; i.e. this bit should result in no functional change.
