s390: add assembler macros for CPU alternatives
[ Upstream commit fba9eb7946251d6e420df3bdf7bc45195be7be9a ]
Add a header with macros usable in assembler files to emit alternative
code sequences. It works analog to the alternatives for inline assmeblies
in C files, with the same restrictions and capabilities.
The syntax is
ALTERNATIVE "<default instructions sequence>", \
"<alternative instructions sequence>", \
"<features-bit>"
and
ALTERNATIVE_2 "<default instructions sequence>", \
"<alternative instructions sqeuence #1>", \
"<feature-bit #1>",
"<alternative instructions sqeuence #2>", \
"<feature-bit #2>"
