Temporarily disable calls to OS::TotalPhysicalMemory to avoid ASSERT when running under the Chrome Sandbox.

This CL reverts the behaviour added in r16983 to avoid calling OS::TotalPhysicalMemory
which fails an assert in the Chrome Sandbox.  It reverts the default
ResourceConstraints behaviour to that of V8 before r16983 (i.e., baseing these
values purely on hard-coded checks against 64bit/32bit and Android/non-Android.
This will be reverted once http://crbug.com/312241 has been resolved.

Use conditional store to replace the receiver with undefined for
strict mode functions and builtins instead of branching code. This
has similar performance characteristics but saves one branch
instruction per strict mode function.

This test suffers heavily from combinatorial explosion. To redemedy
this situation a bit, two independent parsing flags are tested
separately, reducing the runtime by a factor of 4. Furthermore, the
code has been cleaned up a bit.
