Tested with lnt,spec2000 and some other internal benchmarks (same as on ARM)

Performance Regressions - Execution Time
lnt.MultiSource/Applications/hexxagon/hexxagon	5.95%
lnt.MultiSource/Benchmarks/Olden/bh/bh	5.07%
lnt.SingleSource/Benchmarks/Shootout-C++/lists	3.02%
lnt.MultiSource/Applications/sqlite3/sqlite3	2.18%
lnt.MultiSource/Benchmarks/MiBench/telecomm-gsm/telecomm-gsm	1.59%
lnt.MultiSource/Benchmarks/MiBench/telecomm-CRC32/telecomm-CRC32	1.54%
lnt.MultiSource/Benchmarks/BitBench/five11/five11	1.20%
lnt.MultiSource/Benchmarks/TSVC/Expansion-dbl/Expansion-dbl	1.19%

Performance Improvements - Execution Time
lnt.MultiSource/Benchmarks/PAQ8p/paq8p	-16.27%
lnt.MultiSource/Benchmarks/VersaBench/bmm/bmm	-3.78%
lnt.MultiSource/Benchmarks/BitBench/uudecode/uudecode	-3.55%
lnt.SingleSource/UnitTests/Vectorizer/gcc-loops	-3.31%
lnt.MultiSource/Benchmarks/ASC_Sequoia/IRSmk/IRSmk	-2.30%
lnt.MultiSource/Benchmarks/Olden/perimeter/perimeter	-2.07%
lnt.SingleSource/Benchmarks/Polybench/medley/floyd-warshall/floyd-warshall	-1.68%
lnt.SingleSource/Benchmarks/BenchmarkGame/puzzle	-1.20%

Again, no major change in lnt, and spec scores seem unaffected. Same as on ARM, I've seen improvements in other benchmarks.
