The download page says "OS X 10.8 or later", but other pages said 10.7.
Say 10.8 everywhere.
Turns out Go doesn't even compile on OS X 10.7 (details in bug) and we
only run builders for OS X 10.8+, which is likely why 10.7
regressed. Until recently we only had OS X 10.10 builders, even.
We could run 10.7 builders, but there's basically no reason to do so,
especially with 10.12 coming out imminently.

The new SSA backend for s390x can use R0 as a general purpose register.
This change modifies assembly code to either avoid using R0 entirely
or explicitly set R0 to 0.
R0 can still be safely used as 0 in address calculations.

This commit adds the following instructions to support the new SSA
backend for s390x:
32-bit operations:
ADDW
SUBW
NEGW
FNEGS
Conditional moves:
MOVDEQ
MOVDGE
MOVDGT
MOVDLE
MOVDLT
MOVDNE
Unordered branches (for floating point comparisons):
BLEU
BLTU
Modulo operations:
MODW
MODWU
MODD
MODDU
The modulo operations might be removed in a future commit because
I'd like to change DIV to produce a tuple once the old backend is
removed.
This commit also removes uses of REGZERO from the assembler. They
aren't necessary and R0 will be used as a GPR by SSA.

When cmd/compile generates position-independent code on linux
(the -shared flag), it refers to runtime.tlsg as a TLS IE variable.
When cmd/link is linking a PIE executable internally, all TLS IE
relocations are generated by cmd/compile, and the variable they
refer to, runtime.tlsg, is local to the binary. This means we can
optimize this particular IE case to LE, and thus implement IE
support when internally linking.
To do this optimization in the linker, we need to rewrite the
PC-relative MOVD to a constant load. This may seem like an
unconscionable act born of enthusiasm, but it turns out this is
standard operating procedure for linkers. GNU gold does exactly
the same optimization. I spent some time reading it and documented
at least one missing feature from this version.

Also, remove the duplicated entries in the protocol map in different
cases, and just canonicalize the input before looking in the map. Now
it handles any case, including MiXeD cAse.
In the process, add a test that service names for LookupPort are case
insensitive. They were on Windows, but not cgo. Now there's a test and
they're case insensitive in all 3+ paths. Maybe it breaks plan9. We'll
see.

There are also a few false positives that need fixes.
They are noted as such in the whitelists;
they're not worth holding this CL for.
The unsafe pointer check is disabled.
The false positive rate is just too high to be worth it.
There is no cmd/dist/test integration yet.

during all.bash, and that there'll be a fast builder that
checks all platforms (to cover platforms that can't exec).
