David Benjamin 722ba2db77 sha/asm/sha1-x86_64.pl: fix crash in SHAEXT code on Windows. 
RT#4530

(Imported from upstream's 7123aa81e9fb19afb11fdf3850662c5f7ff1f19c.)

We've yet to enable this code, but this confirms that we do indeed need
to get our future all-variants stuff working on Windows as well as
Linux and find an AVX2-capable CI setup on each.

The crash here is caused by some win64-only code using %rax as a frame
pointer (perlasm injects a mov rax,rsp in the prologue of every win64
function).

# sha1_block procedure for x86_64.
#
# It was brought to my attention that on EM64T compiler-generated code
# was far behind 32-bit assembler implementation. This is unlike on
# Opteron where compiler-generated code was only 15% behind 32-bit
# assembler, which originally made it hard to motivate the effort.
# There was suggestion to mechanically translate 32-bit code, but I
# dismissed it, reasoning that x86_64 offers enough register bank
# capacity to fully utilize SHA-1 parallelism. Therefore this fresh
# implementation:-) However! While 64-bit code does perform better
# on Opteron, I failed to beat 32-bit assembler on EM64T core. Well,
# x86_64 does offer larger *addressable* bank, but out-of-order core
# reaches for even more registers through dynamic aliasing, and EM64T
# core must have managed to run-time optimize even 32-bit code just as
# good as 64-bit one. Performance improvement is summarized in the
# following table:
#
# gcc 3.4 32-bit asm cycles/byte
# Opteron +45% +20% 6.8
# Xeon P4 +65% +0% 9.9
# Core2 +60% +10% 7.0
# August 2009.
#
# The code was revised to minimize code size and to maximize
# "distance" between instructions producing input to 'lea'
# instruction and the 'lea' instruction itself, which is essential
# for Intel Atom core.
# October 2010.
#
# Add SSSE3, Supplemental[!] SSE3, implementation. The idea behind it
# is to offload message schedule denoted by Wt in NIST specification,
# or Xupdate in OpenSSL source, to SIMD unit. See sha1-586.pl module
# for background and implementation details. The only difference from
# 32-bit code is that 64-bit code doesn't have to spill @X[] elements
# to free temporary registers.
# April 2011.
#
# Add AVX code path. See sha1-586.pl for further information.
# May 2013.
#
# Add AVX2+BMI code path. Initial attempt (utilizing BMI instructions
# and loading pair of consecutive blocks to 256-bit %ymm registers)
# did not provide impressive performance improvement till a crucial
# hint regarding the number of Xupdate iterations to pre-compute in
# advance was provided by Ilya Albrekht of Intel Corp.
# March 2014.
#
# Add support for Intel SHA Extensions.
