In an effort to at least understand the complete set of things not
working on Alpine Linux, I've been trying to get the build passing
again, even with tests disabled.
The race detector is broken on Alpine. That is #14481 (and #9918).
So disable those tests for now.
Also, internal linking with PIE doesn't work on Alpine yet.
That is #18243. So disable that test for now.
With this CL, all.bash almost passes. There's some cgo test failing
still, but there's no bug yet, so that can be a separate CL.

The assembler reordered the operands of some instructions to put the
first operand into From3. Unfortunately this meant that when the
instructions were printed the operands were in a different order than
the assembler would expect as input. For example, 'MVC $8, (R1), (R2)'
would be printed as 'MVC (R1), $8, (R2)'.
Originally this was done to ensure that From contained the source
memory operand. The current compiler no longer requires this and so
this CL simply makes all instructions use the standard order for
operands: From, Reg, From3 and finally To.

Databases have the following concepts: Statement, Batch, and Session.
A statement is often a single line like:
SELECT Amount from Account where ID = 50;
A batch is one or more statements submitted together for the query
to process. It may be a DELETE, INSERT, two UPDATES and a SELECT in
a single query text.
A session is usually represented by a single database connection.
This often is an issue when dealing with scopes in databases.
Temporary tables and variables can have batch, session, or global
scope depending on the syntax, database, and use.
Furthermore, some databases (sybase and derivatives in perticular)
that prevent certain statements from being in the same batch
and may necessitate being in the same session.
By allowing users to extract a Conn from the database they can manage
session on their own without hacking around it by making connection
pools of single connections (a real workaround presented in issue).
It is tempting to just use a transaction, but this isn't always
desirable or an option if running an interactive session or
alter script set that itself starts transactions.
