allp now has length gomaxprocs, which means none of allp[i] are nil or
in state _Pdead. This lets replace several different styles of loops
over allp with normal range loops.
for i := 0; i < gomaxprocs; i++ { ... } loops can simply range over
allp. Likewise, range loops over allp[:gomaxprocs] can just range over
allp.
Loops that check for p == nil || p.state == _Pdead don't need to check
this any more.
Loops that check for p == nil don't have to check this *if* dead Ps
don't affect them. I checked that all such loops are, in fact,
unaffected by dead Ps. One loop was potentially affected, which this
fixes by zeroing p.gcAssistTime in procresize.

Previously, the read method checked whether the current block
was fully consumed or not based on whether the buffer could be filled
with a non-zero number of bytes. This check is problematic because
zero bytes could be read if the provided buffer is empty.
We fix this case by simply checking for whether the input buffer
provided by the user was empty or not. If empty, we assume that
we could not read any bytes because the buffer was too small,
rather than indicating that the current block was fully exhausted.
This check causes bzip2.Reader to be unable to make progress
on the next block unless a non-empty buffer is provided.
However, that is an entirely reasonable expectation since a
non-empty buffer needs to be provided eventually anyways to
read the actual contents of subsequent blocks.

Instead record in the File whether it is stdout/stderr. This avoids a
race between a call to epipecheck and closing the file.

This is a regression introduced by myself in golang.org/cl/41852,
confirmed by the program that reproduces the crash that can be seen in
the added test.

go command refuses to use GOPATH with empty path elements
(like %GOPATH%=C:\go;). But environment variable change dialog
on Windows 10 produces strings ending with ; (see issue #21928
for a picture). Just accept GOPATH with empty path elements,
and ignore all empty path elements.
Fixes#21928

The current Open method limits the ability for driver maintainers
to expose options for their drivers by forcing all the configuration
to pass through the DSN in order to create a *DB.
This CL allows driver maintainers to write their own initialization
functions that return a *DB making configuration of the underlying
drivers easier.

The reason why adjustctxt wasn't being inlined was reported as:
function too complex: cost 92 exceeds budget 80
However, after tweaking the code to be under the budget limit, we see
the real blocker:
non-leaf function
There is little we can do about this one in particular at the moment.
Create a section with funcs that will need mid-stack inlining to be
inlineable, since this will likely come up again in other cases.
