* vm.c (VM_COLLECT_USAGE_DETAILS): make new VM usage analysis
hooks (old macro name is COLLECT_USAGE_ANALYSIS).
This feature is only for VM developers. (I'm not sure I can use
`VM developers' (the plural form) in this sentence).
If VM_COLLECT_USAGE_DETAILS is not 0, VM enables the following
usage collection features:
(1) insntruction: collect intruction usages.
(2) operand: collect operand usages.
(3) register: collect register usages.
The results are stored in
RubyVM::USAGE_ANALYSIS_INSN for (1, 2),
RubyVM::USAGE_ANALYSIS_INSN_BIGRAM for (1) and
RubyVM::USAGE_ANALYSIS_REGS for (3).
You can stop collecting usages with
RubyVM::USAGE_ANALYSIS_INSN_STOP(),
RubyVM::USAGE_ANALYSIS_OPERAND_STOP(),
RubyVM::USAGE_ANALYSIS_REGISTER_STOP()
for (1), (2), (3) respectively.
You can also change the hook functions by setting
C level global variables
`ruby_vm_collect_usage_func_(insn|operand|register)'
for (1), (2), (3) respectively.
See codes for more details.
* tool/instruction.rb: fix macro names.
* iseq.c (insn_operand_intern): make it export (used in vm.c).
fix to skip several processes if not needed (pointer is 0).
* vm_dump.c: move codes for collection features to vm.c.
* vm_exec.h: rename macro and function names.
* vm_insnhelper.h: ditto.
