75e4fa300c Modify toolchain.gypi to avoid adding -m64 flag on android. 
The -m64 flag isn't supported on Android.  Add a similar gyp condition to avoid
setting the flag on Android in a similar manner to how the -m32 flag is avoided
on android.

starts doing more checks (especially tracking variables and scopes). It will
also show how much having preparse data (or cached data) speeds up the parsing.

When running gyp in parallel mode (soon the default), we need to be able
to find the script by looking at the path relative to the PWD when the
script was originally invoked.

Instead of changing the directory and relying on relative paths, just
use absolute paths (as gyp_chromium does).

The changes are (excluding presubmit.py) mechanical. I added the following
lines after the check and iterated the presubmit script until all errors
went away:

f = open(name, "w");
if contents.endswith('\n\n'):
  f.write(contents[0:-1])
else:

ec9a9ac103 Fix broken pipe caused by commands in toolchain.gypi. 
I sometimes observe broken pipe errors when I run gyp, which causes the gyp
process to fail. This seems to happen if gyp is executed under heavy I/O
pressure.

This change removes the pipes by replacing "echo |" with "< /dev/null".
Technically these are not the same, because "echo |" prints a newline while
"< /dev/null" doesn't, but this difference is not significant in the context of
the commands in toolchain.gypi.

That way, embedders can put the icu sources whereever they want and

a37040b275 Make optimized debug builds link against debug CRT. 
We recently had some XP issues on chromium.win after https://codereview.chromium.org/19384011/.

This might fix it - quote: "The most likely cause of the problem is a gyp (or similar) change that resulted in v8.dll linking against the release version of the crt (for a debug build). There are two MS VC related files: the crt and the c++ std lib (MSVCR100.DLL and MSVCP100D.DLL). The former is set to release, the latter to debug."

I am not entirely sure if this change fits to the linker options for debug level 2.

5666c32d0b Revert windows-specific part of r15937 for debug level 1. 
The change in r15937 might have broken a mozilla test under windows. See https://codereview.chromium.org/19384011/

Each case of debug 0,1,2 is now stated explicitly for better clarity in the msvs section. This causes some minor code duplications, which we can squeeze again after toolchain.gypi is in a stable state.

d0e0ff01ad Revamp v8_optimized_debug options 
This patch changes the definition of v8_optimized_debug==1 to match the release-mode compiler optimization settings (generally, going from -O1 to -O3 on Linux, similar switches for Mac/Win). This produces a minor speed up on Linux, but significant speedups on Mac and Win. This may make it much harder to debug, though.

It also adds a v8_optimized_debug==2 that, in addition to the compiler optimizations, undef's DEBUG and defines DEBUG. This leaves V8_ENABLE_CHECKS alone (so that the assertions are still enabled), but otherwise basically matches a release mode build.

Builds with v8_optimized_debug==2 roughly match a Release mode build for speed; the V8_ENABLE_CHECKS checks appear to have minimal performance impact (maybe 5-10%, unlike what was previously thought). In addition, switching from the previous optimization settings makes a significant improvement on Mac and Win (50% or more), and switching from DEBUG to NDEBUG makes a significant improvement (another 50% or more).

Note that using v8_optimized_debug==2 may also cause some v8 tests to fail. This is currently is believed to be acceptable.
