  [mlir][Arith] Let integer range narrowing handle negative values (#119642)

Update integer range narrowing to handle negative values.

The previous restriction to only narrowing known-non-negative values
wasn't needed, as both the signed and unsigned ranges represent bounds
on the values of each variable in the program ... except that one might
be more accurate than the other. So, if either the signed or unsigned
interpretetation of the inputs and outputs allows for integer narrowing,
the narrowing is permitted.

This commit also updates the integer optimization rewrites to preserve
the stae of constant-like operations and those that are narrowed so that
rewrites of other operations don't lose that range information.

  [llvm-gsymutil] Fix dumping of call sites for merged functions (#119759)

Currently, when dumping the contents of a GSYM there are three issues:
- Callsite information is not displayed for merged functions - this is
because of a bug in `CallSiteInfoLoader::buildFunctionMap` where when
enumerating through `Func.MergedFunctions` - we enumerate by value
instead of by reference.
- There is no variable indent for printing callsite info - meaning that
when printing callsites for merged functions, the indent will be
different than the other info of the merged function. To address this we
add configurable indent for printing callsite info
- Callsite info is printed right after merged function info. Meaning
that if the merged function also has call site information, the parent's
callsite info will appear right after the merged function's callsite
info - leading to confusion. To address this we print the callsite info
first, then the merged functions info.

This change addresses all the above 3 issues.
