9903164536 Merge patches from JeremyF, to do lazy eflags updating:
- D flag is seperated from the rest (OSZCAP)

- Minimise transfers between real and simulated %eflags since these
  are very expensive.

61-special-d

Make the D flag special. Store it separately in the baseblock rather
than in EFLAGs. This is because it is used almost completely unlike
the other flags, and mashing them together just makes maintaining
eflags hard.

62-lazy-eflags

Implements lazy eflags save and restore. Helps a lot.

Hopefully more documentation to follow.

df503439c5 Overview:
- Factored out a lot of commonality between AddrCheck and MemCheck.  Basic
    idea is that common code goes into a single file in MemCheck, and AddrCheck
    peeks in and "borrows" it.

    More or less, only identical code or identical-with-respect-to-subtypes
    code was factored out.

    Identical-with-respect-to-subtypes means that some enum types (SuppKind,
    ErrorKind, etc) were merged because they were identical except that
    MemCheck had some extra constants.  So some of the code borrowed by
    AddrCheck contains cases it never needs.  But that's not so bad, avoiding
    the duplication is IMHO more important.

Removed:
  - ac_include.h, it wasn't necessary

  - All the old debugging stuff from ac_main.c (printing shadow regs, not
    applicable for AddrCheck).

  - MANUAL_DEPS from memcheck/Makefile.am because it wasn't doing anything

  - Some unnecessary crud from addrcheck/Makefile.am

Added:
  - memcheck/mc_common.{c,h}
  - memcheck/mc_constants.h
  - addrcheck/ac_common.c, which simply #includes memcheck/mc_common.c.  This
    hack was required because there is no way (that I could work out) to tell
    Automake that it should build ../memcheck/mc_common.o before building
    AddrCheck.

Changed:
  - a lot of prefixes from SK_ to MC_;  only core/skin interface functions are
    prefixed with SK_ now.  This makes it clear which functions are from the
    core/skin interface, and for AddrCheck it's clear which functions are
    shared with/borrowed from MemCheck.  Changed some related prefixes for
    consistency.

  - Also factored out some duplication within AddrCheck -- some accessibility
    checking was needlessly split up into separate read and write checks that
    did the same thing.

Unchanged:
  - I considered moving the leak detector out of core into mc_common.c, but
    didn't, because it constantly accesses ShadowChunk fields and converting to
    get/set methods would have been a total pain.

  - Left old debugging stuff in for MemCheck, although I seriously doubt it
    would still work.

534ab14977 Moved the following macros, which were defined multiple times in multiple
files, into vg_skin.h:

    uInstr0, uInstr1, uInstr2, uInstr3, nameIReg, nameISize, nameSReg,
    newTemp, newShadow, uLiteral, uCCall

As macros they avoid namespace problems (they expand to VG_(whatever)) so
this should work fine.

089e7e3bcb Updated file descriptions in the copyright notices to reflect the core/skin
split.  Each skin now has its own two-line description.

41a0bcbbbb Changes made so that skin error "report this bug to" messages are distinguished
from core error ones:

  - Split up VG_(panic) into VG_(core_panic) and VG_(skin_panic)

  - Likewise, split vg_assert into vg_assert and sk_assert

  - Added a new need string: `bug_reports_to'

  - Removed VG_(skin_error) which was a previous wussy attempt at this change.
    This removed the need for the hacky redeclaration of VG_(skin_error) in
    vg_profile.c, which is good.

At the moment, Julian and Nick's email addresses are hard-coded into each skin
individually, rather than using a #define in vg_skin.h, because that didn't
feel quite right to me...  jseward@acm.org is still done with a #define for
core errors, though.

4cd67f62e6 Converted all functions visible from vg_skin.h with names in CamelCaps to
use_under_scores instead, to be consistent.

Also added some missing 'extern's on function declarations in vg_skin.h.

Also added a quick note in vg_regtest.in on the simplest way to run regression
tests.

f1689b96db Changed lots of files for the new core/ + skin/ directory structure:
- changed lots of Makefile.am files
   - changed configure.in
   - changed lots of #include lines for changed file names
   - changed lots of file headers n footers for changed file names
   - changed vg_regtest to handle new directory structure -- recursively
     traverses subdirectories for .vgtest test files
   - changed lots of paths in memcheck/ regression test expected outputs
