Enabling the HIGH_ENTROPY_VA flag allows the operating system to use
addresses outside of the 32-bit range before memory exhaustion. This
results in a higher entropy implementation of ASLR when used with the
DYNAMIC_BASE flag.
* include/coff/pe.h: Add HIGH_ENTROPY_VA flag
* ld/emultempl/pep.em: Add --high-entropy-va switch
* ld/ld.texinfo: Document the --high-entropy-va switch
