[SCEVAffinator] Do not scan redundantly for parameters
In r286430 "SCEVValidator: add new parameters resulting from constant
extraction" we added functionality to scan for parameters after constant
extraction has taken place to ensure newly created parameters are correctly
registered. This addition made the already existing registration of parameters
redundant. Hence, we remove the corresponding call in this commit.
An alternative solution would have been to also perform constant extraction when
validating SCEV expressions and to then scan for parameters when validating
a SCEV expression. However, as SCEV validation is used during SCoP detection
where we want to be especially fast, adding additional functionality on this
hot path should be avoided if good alternatives exist. In this case, we can
choose to continue to only transform SCEV expression when actually modeling
them. As all transformations we perform are expected to not change the validity
of the SCEV expressions, this solution seems preferable.

may accept an icmp that is defined within a loop which itself dominates, but

This commit fixes the problem by removing "LLVM_NATIVE_ARCH MATCHES ARM"
from CMakeLists.txt so that LIBCXXABI_USE_LLVM_UNWINDER will only be
defined when LLVM unwinder is enabled.
We need LIBCXXABI_USE_LLVM_UNWINDER becase there is a subtle difference
between the unwinder from libgcc and the one from libunwind_llvm. For
the unwinder from libgcc, we have to initialize register r12 with the
address of _Unwind_Control_Block; otherwise,
_Unwind_GetLanguageSpecificData() and _Unwind_GetRegionStart() won't
work properly. Consequently, there is an extra _Unwind_SetGR() when
LLVM unwinder is disabled. Check cxa_personality.cpp for details.

Fix PR28366: Handle variables from enclosing local scopes more gracefully during constant expression evaluation.
Only look for a variable's value in the constant expression evaluation activation frame, if the variable was indeed declared in that frame, otherwise it might be a constant expression and be usable within a nested local scope or emit an error.
