During execution functions are found in two function maps: first in the
template, then in the global function map. By default, no functions are defined
in the template but the Funcs method can be used to add them.

Predefined global functions are named as follows.

# Basics

A stream of gobs is self-describing. Each data item in the stream is preceded by
a specification of its type, expressed in terms of a small set of predefined
types. Pointers are not transmitted, but the things they point to are
transmitted; that is, the values are flattened. Nil pointers are not permitted,
as they have no value. Recursive types work fine, but

constexpr absl::string_view kFlexOpNamePrefix = "Flex";
// Don't fallback to Flex op if this attribute is set. This attribute is
// transient and is only used inside this pass. First, the pass looks for
// predefined patterns and set this attribute to ops in the patterns. Then,
// when parsing the function, if find ops with this attribute, the pass
// remove the attribute and skip further processing on those ops.

// graph and pass them as arguments to the TPU graph (via `TPUPartitionedCall`).
// If this happens, the XLA compiler cannot recognize such arguments as
// constants and may result in an error.

// A set of predefined ops and operand indices is used to determine whether an
// operand is a target for constant duplication.
