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).

Third stage of implementing an out-of-line constant pool for Arm.  This CL adds
a ConstantPool field to Code objects and initializes the pp register on
function entry, and saves the pp register on the stack frame. The ConstantPool
object is always empty and is unused currently.

If concurrent recompilation finishes before OSR, then OSR replaces
the old optimized code without evicting it from the optimized code map.

New functions can get the old optimized code from the optimized code map,
but the old code could be already deoptimized.

Goals:
 - easier to read, more suitable identifiers.
 - better distinction between compiling optimized/unoptimized code
 - compiler does not install code on the function.
 - easier to add features (e.g. caching optimized code for osr).
 - remove unnecessary code.

It's of much use when information about function calls is shown on the Events timeline in DevTools: instead of referencing to v8natives.js where bound functions are created, we'll be able to show real function data (name, resource, script line and column numbers) retrieved from original functions.
