tcg: rework TCG helper flags
The current helper flags, TCG_CALL_CONST and TCG_CALL_PURE might be confusing and doesn't provide enough granularity for some helpers (FP helpers for example). This patch changes them into the following helpers flags: - TCG_CALL_NO_READ_GLOBALS means that the helper does not read globals, either directly or via an exception. They will not be saved to their canonical location before calling the helper. - TCG_CALL_NO_WRITE_GLOBALS means that the helper does not modify any globals. They will only be saved to their canonical locations before calling helpers, but they won't be reloaded afterwise. - TCG_CALL_NO_SIDE_EFFECTS means that the call to the function is removed if the return value is not used. It provides convenience flags, to avoid helper definitions longer than 80 characters. It also provides compatibility flags, and updates the documentation.
