[PATCH-for-10.1 05/12] tcg: Use TCGContext::insn_start_words in tcg_gen_insn_start()

[Philippe Mathieu-Daudé]

In tb_gen_code() we set TCGContext::insn_start_words to
TARGET_INSN_START_WORDS:

290 TranslationBlock *tb_gen_code(...)
293 {
...
351     tcg_ctx->insn_start_words = TARGET_INSN_START_WORDS;

This definition is expanded to:

 11 # define TARGET_INSN_START_WORDS (1 + TARGET_INSN_START_EXTRA_WORDS)

Directly use the identical tcg_ctx->insn_start_words variable.
