Adam Langley 1168fc72fc bn/asm/rsaz-avx2.pl: constant-time gather procedure. 
(Imported from upstream's 08ea966c01a39e38ef89e8920d53085e4807a43a)

Performance penalty is 2%.

(This is part of the fix for CVE-2016-0702.)

# While original submission covers 512- and 1024-bit exponentiation,
# this module is limited to 512-bit version only (and as such
# accelerates RSA1024 sign). This is because improvement for longer
# keys is not high enough to justify the effort, highest measured
# was ~5% on Westmere. [This is relative to OpenSSL 1.0.2, upcoming
# for the moment of this writing!] Nor does this module implement
# "monolithic" complete exponentiation jumbo-subroutine, but adheres
# to more modular mixture of C and assembly. And it's optimized even
# for processors other than Intel Core family (see table below for
# improvement coefficients).
