- "size"; optimizes for minimal code size, the default.
- "speed"; optimizes for speed over code size.
- "max"; turns on link time code generation and whole
program optimization, which is very expensive and should
be used sparingly.
Note that this change by itself lowers the optimization level to "size" for all targets. Separate changes to the V8 and WebKit repos will be needed to bring up their optimization levels to WPO.

Also, remove the Optimization hard-coded flags that turned out not to be adjustable as well.

These vsprops used to be used to setup the branding #defines.
This is now handled in common.gypi.
This is an incremental step toward dropping vsprops entirely for release.

We need some functions from dbghelp.dll to implement backtrace logic in base/debug_util_win.cc. This change will stage things so adding the new function calls won't break everyone. The delay load is in essential.vsprops because everyone will need it in order to link base after the backtrace code is added.

Doing a full build seems always fine. The issue is for incremental builds, it corrupts the PDBs. Errors look like:
glue.lib(autofill_form.obj) : fatal error LNK1318: Unexpected PDB error; RPC (23) '(0x000006BA)'
...\xmemory(155) : error C2471: cannot update program database '...\debug\obj\plugin_tests\vc80.pdb'
We'll probably need to upgrade to VS2008 to add it back.

and better-thought-out Hammer env.Bits() idioms:
* env['PLATFORM'] == 'win32' => env.Bit('windows')
* env['PLATFORM'] == 'posix' => env.Bit('linux')
* env['PLATFORM'] == 'darwin' => env.Bit('mac')
New idioms:
* env.Bit('posix') => really does mean "any POSIX platform"
* env.AnyBits('mac', 'linux') => specifically mac or linux, excluding
other POSIX platforms
Where we were using compound conditionals (e.g., "env['PLATFORM'] in
('posix', 'darwin')") I tried to take my best shot at translating
the intent (i.e., "env.Bits('posix')" for something POSIX, "not
env.Bits('mac')" for something not yet ported to Mac, etc.)

We keep the current behavior for regular builds:
- debug: DCHECKS enabled.
- release: DCHECKS present but inactive; can be activated through the command line.
Now we add a new behavior for official builds:
- dchecks optimized away.

of an internal $CHROMIUM_INCREMENTAL_FLAGS construction variable.

* Add third_party/purify/pure_api.c to the base\base_lib.scons sources.
* Support specification of CHROME_BUILD_TYPE (and CHROMIUM_BUILD
while we're here) either on the command line or as an
external environment variable.
* Fix syntax error in release_impl_purify.scons (previously unused).
* Add a central $CHROMIUM_CC_OPT_FLAGS variable (included in $CCFLAGS)
that can be used to set explicitly the optimization level without
having to worry about optimization flags being pulled in from other
settings files.

build\*.scons structure (mirroring build\*.vsprops files):
* Use env.ApplySConscript() instead of env.SConscript with a
hand-crafted dictionary defining 'env'.
* Move various CPPPATH, CCFLAGS, CPPDEFINES, LIBS and LIBPATH
definitions from build/SConscript.main and target-specific
*.scons files into the build\*.scons files that mirror the
existing build\*.vsprops hierarchy.
* Use the new build\{debug,release}.scons files to update the
windows_dbg and windows_opt construction environments.
* Mirror current support for CHROME_BUILD_TYPE and CHROMIUM_BUILD
external environment variables.
* Remove hard-coded /TP options.
* Massage $CXXFLAGS to remove $CCFLAGS, avoiding duplication of options
on command lines. Handle the ripple effect in $PCHCOM by adding
$CCFLAGS back to that command line.
* Delete hammer's default settings of {CC,LINK}FLAGS_{DEBUG,OPTIMIZED}
so they don't pollute our construction environments.
* Update chrome config to link against v8 for opt, v8_g for dbg.
* Get rid of fragile by-hand order of using_net.scons before other
using_*.scons files. We're now using --start-group and --end-group
on Linux to deal with dependency cycles in libraries.

OmitFramePointers="false" doesn't work since this attribute would have needed to be tri-state to work correctly.

- I assume we will need to build Debug version also for Google Chrome.
- Code changes will come soon that will rely on GOOGLE_CHROME_BUILD being defined to add Google branding.
- Currently I do not want to change the default behavior so it is inhreiting chromium_build_google_chrome.vsprops. Once buildbot scripts have been configured properly and we know what to do for developers machines, we will inherit chromium_build$CHROMIUM_BUILD.vsprops
