BlockGenerator: Recompute values from SCEV before handing back the original values
This patch moves the SCEV based (re)generation of values before the checking for
scop-constant terms. It enables us to provide SCEV based replacements, which
are necessary to correctly generate OpenMP subfunctions when using the SCEV
based code generation.
When recomputing a new value for a value used in the code of the original scop,
we previously directly returned the same original value for all scop-constant
expressions without even trying to regenerate these values using our SCEV
expression. This is correct when the newly generated code remains fully in the
same function, however in case we want to outline parts of the newly generated
scop into subfunctions, this approach means we do not have any opportunity to
update these values in the SCEV based code generation. (In the non-SCEV based
code generation, we can provide such updates through the GlobalMap). To ensure
we have this opportunity, we first try to regenerate scalar terms with our SCEV
builder and will only return scop-constant expressions if SCEV based code
generation was not possible.
This change should not affect the results of the existing code generation
passes. It only impacts the upcoming OpenMP based code generation.
This commit also adds a test case. This test case passes before and after this
commit. It was added to ensure test coverage for the changed code.

add the following instructions to the first basic block :
%temp = alloca %struct.x, align 8

%tt2 = llvm.nvvm.cvt.gen.to.param %tt2
%tempd = bitcast i8 addrspace(101) * to %struct.x addrspace(101) *
%tv = load %struct.x addrspace(101) * %tempd
store %struct.x %tv, %struct.x * %temp, align 8

ARM: try to add extra CS-register whenever stack alignment >= 8.
We currently try to push an even number of registers to preserve 8-byte
alignment during a function's prologue, but only when the stack alignment is

less frequently for 16-byte stack alignment).

ARM/Dwarf: correctly align stack before callee-saved VPRs
We were making an attempt to do this by adding an extra callee-saved GPR (so
that there was an even number in the list), but when that failed we went ahead
and pushed anyway.
This had a couple of potential issues:
+ The .cfi directives we emit misplaced dN because they were based on
PrologEpilogInserter's calculation.
+ Unaligned stores can be less efficient.
+ Unaligned stores can actually fault (likely only an issue in niche cases,
but possible).
This adds a final explicit stack adjustment if all other options fail, so that
the actual locations of the registers match up with where they should be.

Analysis: Make isSafeToSpeculativelyExecute fire less for divides
Divides and remainder operations do not behave like other operations
when they are given poison: they turn into undefined behavior.
It's really hard to know if the operands going into a div are or are not
poison. Because of this, we should only choose to speculate if there
are constant operands which we can easily reason about.

Provide gmlt-like inline scope information in the skeleton CU to facilitate symbolication without needing the .dwo files
Clang -gsplit-dwarf self-host -O0, binary increases by 0.0005%, -O2,
binary increases by 25%.
A large binary inside Google, split-dwarf, -O0, and other internal flags
(GDB index, etc) increases by 1.8%, optimized build is 35%.
The size impact may be somewhat greater in .o files (I haven't measured
that much - since the linked executable -O0 numbers seemed low enough)
due to relocations. These relocations could be removed if we taught the
llvm-symbolizer to handle indexed addressing in the .o file (GDB can't
cope with this just yet, but GDB won't be reading this info anyway).
Also debug_ranges could be shared between .o and .dwo, though ideally
debug_ranges would get a schema that could used index(+offset)
addressing, and move to the .dwo file, then we'd be back to sharing
addresses in the address pool again.
But for now, these sizes seem small enough to go ahead with this.
Verified that no other DW_TAGs are produced into the .o file other than
subprograms and inlined_subroutines.
