[PULL 04/10] tcg: Increase the static number of temporaries

[Richard Henderson]

This isn't a total or permanent solution to the problem of running
out of temporaries, but it puts off the issue for a bit.

Make the assert in tcg_temp_alloc unconditional.  If we do run out
of temps, this can fail much later as a weird SIGSEGV, due to the
buffer overrun of the temp array.

Remove the inlines from tcg_temp_alloc and tcg_global_alloc.
