The language spec only requires that floating point values be represented with 256 bits, which is about 1e75. The issue11371 test was assuming that the compiler could represent 1e100. Adjusting the test so that it only assumes 256 bits of precision still keeps the test valid, and permits it to pass when using the gofrontend.
