Canonicalize declaration pointers when forming APValues.

References to different declarations of the same entity aren't different
values, so shouldn't have different representations.

Recommit of e6393ee813178e9d3306b8e3c6949a4f32f8a2cb with fixed
handling for weak declarations. We now look for attributes on the most
recent declaration when determining whether a declaration is weak.

PR47555: Inheriting constructors are implicitly definable.

Don't forget to define them if they're constexpr and used inside a
template; we might try to evaluate a call to them before the template is

[NewPM] Port -print-alias-sets to NPM

Really it should be named print<alias-sets>, but for the sake of
changing fewer tests, added a TODO to rename after NPM switch and test

[IRSim] Adding IR Instruction Mapper

This introduces the IRInstructionMapper, and the associated wrapper for
instructions, IRInstructionData, that maps IR level Instructions to
unsigned integers.

Mapping is done mainly by using the "isSameOperationAs" comparison
between two instructions.  If they return true, the opcode, result type,
and operand types of the instruction are used to hash the instruction
with an unsigned integer.  The mapper accepts instruction ranges, and
adds each resulting integer to a list, and each wrapped instruction to
a separate list.

At present, branches, phi nodes are not mapping and exception handling
is illegal.  Debug instructions are not considered.

The different mapping schemes are tested in

[mlir] expose affine map to C API

This patch provides C API for MLIR affine map.
- Implement C API for AffineMap class.
- Add Utils.h to include/mlir/CAPI/, and move the definition of the CallbackOstream to Utils.h to make sure mlirAffineMapPrint work correct.
- Add TODO for exposing the C API related to AffineExpr and mutable affine map.

[libunwind][DWARF] Fix end of .eh_frame calculation

* When .eh_frame is located using .eh_frame_hdr (PT_GNU_EH_FRAME), the
   start of .eh_frame is known, but not the size. In this case, the
   unwinder must rely on a terminator present at the end of .eh_frame.
   Set dwarf_section_length to UINTPTR_MAX to indicate this.

* Add a new field, text_segment_length, that the FrameHeaderCache uses
   to track the size of the PT_LOAD segment indicated by dso_base.

* Compute ehSectionEnd by adding sectionLength to ehSectionStart,
   never to fdeHint.

Fixes PR46829.

[PowerPC] Fix store-fptoi combine of f128 on Power8

llc would crash for (store (fptosi-f128-i32)) when -mcpu=pwr8, we should
not generate FP_TO_(S|U)INT_IN_VSR for f128 types at this time. This
patch fixes it.
