This is a follow-up to Emilio's patch set.

My primary changes to Emilio's patches are to the first patch, in
merging the existing implementations from tcg/ppc/tcg-target.inc.c
into util/cacheinfo.c.

Then I've a few follow-up patches to take advantage of the new TB
placement for arm platforms.  I've had a look at the asm output for
ppc64 and s390x, and don't see anything obvious that can be improved.

Changes since v4:
  * The first patch reorganized a bit for aarch64 and ppc64.
    Re-tested on win32, for which there was a Werror.
    Incorporated feedback from Emilio re MacOS.
  * Fixed the short description for the tcg/arm patches.

Emilio G. Cota (2):
  util: add cacheinfo
  tcg: allocate TB structs before the corresponding translated code

Richard Henderson (5):
  tcg/aarch64: Use ADR in tcg_out_movi
  tcg/arm: Use indirect branch for goto_tb
  tcg/arm: Remove limit on code buffer size
  tcg/arm: Try pc-relative addresses for movi
  tcg/arm: Use ldr (literal) for goto_tb
