Revert "[HIP] Fix -gsplit-dwarf option"

This reverts commit e50465ecefc964e5700df26fc7e02a673eed085a

Commit d4dd961300588ce7e50625a1947befb45e3a0c42 by koraq
Fixes complexity of map insert_or_assign with a hint.

Mitsuru Kariya reported the map operations insert_or_assign with a hint
violates the complexity requirement. The function no longer uses a lower_bound,
which caused the wrong complexity.

Fixes PR38722: [C++17] std::map::insert_or_assign w/ hint violate complexity requirements

[ConstantFolding] add undef handling for fmin/fmax intrinsics

The output here may not be optimal (yet), but it should be
consistent for commuted operands (it was not before) and
correct. We can do better by checking FMF and NaN if needed.

Code in InstSimplify generally assumes that we have already
folded code like this, so it was not handling 2 constant
inputs by commuting consistently.
