80e2a2f817 Target: Change various section classifiers in TargetLoweringObjectFile to take a GlobalObject.
These functions are about classifying a global which will actually be
emitted, so it does not make sense for them to take a GlobalValue which may
for example be an alias.

Change the Mach-O object writer and the Hexagon, Lanai and MIPS backends to
look through aliases before using TargetLoweringObjectFile interfaces. These
are functional changes but all appear to be bug fixes.

a6b9e20623 Revert "[AMDGPU] Emit read-only data to .rodata for hsa"
This reverts commit r276298.

Data stored in .rodata can have a negative offset from .text, but we
don't support negative values in relocations yet.

This caused a regression in one of the amp conformance tests:
5_Data_Cont/5_2_a_v/5_2_3_m/Assignment/Test.02.01

66eb4d17bb AMDGPU/SI: Add support for AMD code object version 2.
Summary:
Version 2 is now the default.  If you want to emit version 1, use
the amdgcn--amdhsa-amdcov1 triple.

7d2a810fef AMDGPU/SI: Emit constant arrays in the .text section
Summary:
This allows us to remove the END_OF_TEXT_LABEL hack we had been using
and simplifies the fixups used to compute the address of constant
arrays.
