ART: Split out PROT_EXEC from custom low-4GB allocator To address the known issue that denials for executable memory can lead to the custom low-4GB allocator being very slow, split the allocation into two parts. First allocate without PROT_EXEC, then try to mprotect with the originally requested flags.
