             nThis:


On a number of the JavaScriptCore tests, SquirrelFish fails with an assertion
during codegen if there is a large number of temporaries. These failures do not
get seem to get reported by run-javascriptcore-tests. An example is
ecma/Array/15.4.5.2-2.js, which fails with the following assertion:

ASSERTION FAILED: m_temporaries.size() < m_temporaries.capacity()
(./VM/CodeGenerator.cpp:296 KJS::RegisterID*
KJS::CodeGenerator::newTemporary())

Many of the array tests fail for the same reason.
