David Benjamin fdd8e9c8c7 Switch perlasm calling convention. 
Depending on architecture, perlasm differed on which one or both of:

  perl foo.pl flavor output.S
  perl foo.pl flavor > output.S

Upstream has now unified on the first form after making a number of
changes to their files (the second does not even work for their x86
files anymore). Sync those portions of our perlasm scripts with upstream
and update CMakeLists.txt and generate_build_files.py per the new
convention.

This imports various commits like this one:
184bc45f683c76531d7e065b6553ca9086564576 (this was done by taking a
diff, so I don't have the full list)

Confirmed that generate_build_files.py sees no change.

BUG=14

## Constant-time SSSE3 AES core implementation.
## version 0.1
##
## By Mike Hamburg (Stanford University), 2009
## Public domain.
##
## For details see http://shiftleft.org/papers/vector_aes/ and
## http://crypto.stanford.edu/vpaes/.

# September 2011.
#
# Interface to OpenSSL as "almost" drop-in replacement for
# aes-x86_64.pl. "Almost" refers to the fact that AES_cbc_encrypt
# doesn't handle partial vectors (doesn't have to if called from
# EVP only). "Drop-in" implies that this module doesn't share key
# schedule structure with the original nor does it make assumption
# about its alignment...
#
# Performance summary. aes-x86_64.pl column lists large-block CBC
# encrypt/decrypt/with-hyper-threading-off(*) results in cycles per
# byte processed with 128-bit key, and vpaes-x86_64.pl column -
# [also large-block CBC] encrypt/decrypt.
#
# aes-x86_64.pl vpaes-x86_64.pl
#
# Core 2(**) 29.6/41.1/14.3 21.9/25.2(***)
# Nehalem 29.6/40.3/14.6 10.0/11.8
# Atom 57.3/74.2/32.1 60.9/77.2(***)
# Silvermont 52.7/64.0/19.5 48.8/60.8(***)
#
# (*) "Hyper-threading" in the context refers rather to cache shared
# among multiple cores, than to specifically Intel HTT. As vast
# majority of contemporary cores share cache, slower code path
# is common place. In other words "with-hyper-threading-off"
# results are presented mostly for reference purposes.
#
# (**) "Core 2" refers to initial 65nm design, a.k.a. Conroe.
#
# (***) Less impressive improvement on Core 2 and Atom is due to slow
# pshufb, yet it's respectable +36%/62% improvement on Core 2
# (as implied, over "hyper-threading-safe" code path).
