Do the cast to uintptr_t within the helper, so that the compiler
can type check the pointer argument. We can also do some more
sanity checking of the index argument.

Notes:
- Did not convert {num,max}_insns, since the corresponding code
will go away in the next patch.
- ctx->pc becomes ctx->base.pc_next, and ctx->next_pc becomes
ctx->pc_succ_insn.
While at it, convert the remaining tb->cflags readers to tb_cflags().

Previously the mycycle/minstret CSRs and rdcycle/rdinstret
psuedo instructions would return the time as a proxy for an
increasing instruction counter in the absence of having a
precise instruction count. If QEMU is invoked with -icount,
the mcycle/minstret CSRs and rdcycle/rdinstret psuedo
instructions will return the instruction count.
