These functions are used from within a compilation unit so we can
make them static, for better binary size. This changeset reduces
the size of generated ruby binary from 26,590,128 bytes to
26,584,472 bytes on my macihne.
only when its receiver and the argument are both Integers.
Since 6bedbf4625, Integer#[] has supported a range extraction.
This means that Integer#[] now accepts multiple arguments, which made
the method very slow unfortunately.
This change fixes the performance issue by adding a special handling for
its traditional use case: `num[idx]` where both `num` and `idx` are
Integers.
* numeric.c (int_pow): fix infinite loop in the case of y equal 1
and power of x does not overflow.

that it creates a new instance, but is not an instance method.
* complex.c (rb_complex_polar): deprecated.

In C, division by zero is undefined, even if the expression is double
(cf: ISO/IEC 9899:1990 section 6.3.5). OTOH we have tests about such
operations and results, means we expect no exceptional situation shall
occur. We need to carefully reroute the situation, and generate what
is needed.

PS: Recently (last two decades), C have Annex. F document. It
normatively specifies that the division operator is IEEE 754's
division operator (cf: ISO/IEC 9899:1999 section F.3). If we could
move to such newer version this could be no problem. But that is not
possible today.

allocating intermediate Complex objects, and avoid unexpected
NaNs.

This commit introduces new core class Enumerator::ArithmeticSequence.
Enumerator::ArithmeticSequence is a subclass of Enumerator, and
represents a number generator of an arithmetic sequence.
After this commit, Numeric#step and Range#step without blocks
returned an ArithmeticSequence object instead of an Enumerator.
This class introduces the following incompatibilities:
- You can create a zero-step ArithmeticSequence,
and its size is not ArgumentError, but Infinity.
- You can create a negative-step ArithmeticSequence from a range.

tool/ruby_vm/views/_insn_name_info.erb: on Linux, rb_vm_insn_name_offset
was needed to compile with --jit-debug (Usually --jit-debug requires
more symbols than the situation without --jit-debug because -O2 skips
some functions to compile).
vm.c: when running transform_mjit_header.rb with --jit-wait,
rb_source_location_cstr was repoted to be missing.
string.c: ditto, for rb_str_eql
numeric.c: ditto, for rb_float_eql
