[bugpoint] Increase the default memory limit for subprocesses to 300MB.
Summary: Currently shared library builds (BUILD_SHARED_LIBS=ON in cmake) fail three bugpoint tests (BugPoint/remove_arguments_test.ll, BugPoint/crash-narrowfunctiontest.ll, and BugPoint/metadata.ll). If I run the bugpoint commands that llvm-lit runs with without -silence-passes I see errors such as this: opt: error while loading shared libraries: libLLVMSystemZInfo.so: failed to map segment from shared object: Cannot allocate memory It seems that the increased size of the binaries in a shared library build is causing the subprocess to exceed the 100MB memory limit. This patch therefore increases the default limit to a level at which these tests pass.
