H.J. Lu 0ce398f106 Add --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi]
This patch adds --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi]

sections.  We always generate .zdebug_* section since section names have
been finalized and they can't be changed easily when compression is
being performed.

H.J. Lu 151411f8af Add SHF_COMPRESSED support to gas and objcopy
This patch adds --compress-debug-sections={none|zlib|zlib-gnu|zlib-gabi}
options to gas and objcopy for ELF files. They control how DWARF debug
sections are compressed.  --compress-debug-sections=none is equivalent to
--nocompress-debug-sections.  --compress-debug-sections=zlib and
--compress-debug-sections=zlib-gnu are equivalent to
--compress-debug-sections.  --compress-debug-sections=zlib-gabi compresses
DWARF debug sections with SHF_COMPRESSED from the ELF ABI.  No linker
changes are required to support SHF_COMPRESSED.

H.J. Lu 80b8656cba Limit multi-byte nop instructions to 10 bytes
There is no performance advantage to use multi-byte nop instructions
greater than 10 bytes.  This patch limits multi-byte nop instructions
to 10 bytes.  Since there is only one way to encode multi-byte nop
instructions now, it also removed redundant nop tests.
