This function gives T's actual numerical value, influenced by the

bit pattern would be 128.
This is the right choice when operating on groups of INTEGER_CSTs
that might have different signedness or precision. It is also the
right choice in code that specifically needs an approximation of
infinite-precision arithmetic instead of normal modulo arithmetic.
The approximation of infinite precision is good enough for realistic
numbers of additions and subtractions of INTEGER_CSTs (where
"realistic" includes any number less than 1 << 31) but it cannot
represent the result of multiplying the two largest supported
INTEGER_CSTs. The overflow-checking form of wi::mul provides a way
of multiplying two arbitrary INTEGER_CSTs and checking that the
result is representable as a widest_int.
Note that any overflow checking done on these values is relative to
the range of widest_int rather than the range of a TREE_TYPE.
Calling this function should have no overhead in release builds,
so it is OK to call it several times for the same tree. If it is
useful for readability reasons to reduce the number of calls,

the target's address size in bits.
This is the right choice when operating on bit or byte counts as
untyped numbers rather than M-bit values. The wi::to_widest comments
about addition, subtraction and multiplication apply here: sequences
of 1 << 31 additions and subtractions do not induce overflow, but
multiplying the largest sizes might. Again,
wi::tree_to_offset_ref wt = wi::to_offset (t);

As with machine registers, signedness is determined by the operation
rather than the operands; for example, there is a distinction between
signed and unsigned division.
This is the right choice when operating on values with the same type
using normal modulo arithmetic. The overflow-checking forms of things
