As Andy Balholm noted in #11207:

"RFC2616 §4.2 says that a header's field-content can consist of *TEXT,
and RFC2616 §2.2 says that TEXT is <any OCTET except CTLs, but
including LWS>, so that would mean that bytes greater than 128 are
allowed."

This is a partial rollback of the strictness from
https://golang.org/cl/11207 (added in the Go 1.6 dev cycle, only
released in Go 1.6beta1)

Fixes #11207

Adding the evconst(n) call for OANDAND and OOROR in
golang.org/cl/18262 was originally just to parallel the above iscmp
branch, but upon further inspection it seemed odd that removing it
caused test/fixedbugs/issue6671.go's

    var b mybool
    // ...
    b = bool(true) && true // ERROR "cannot use"

to start failing (i.e., by not emitting the expected "cannot use"
error).

The problem is that evconst(n)'s settrue and setfalse paths always
reset n.Type to idealbool, even for logical operators where n.Type
should preserve the operand type.  Adding the evconst(n) call for
OANDAND/OOROR inadvertantly worked around this by turning the later
evconst(n) call at line 2167 into a noop, so the "n.Type = t"
assignment at line 739 would preserve the operand type.

However, that means evconst(n) was still clobbering n.Type for ONOT,
so declarations like:

    const _ bool = !mybool(true)

were erroneously accepted.

f90b48e0 intended to require the stack barrier lock in all cases of
sigprof that walked the user stack, but got it wrong. In particular,
if sp < gp.stack.lo || gp.stack.hi < sp, tracebackUser would be true,
but we wouldn't acquire the stack lock. If it then turned out that we
were in a cgo call, it would walk the stack without the lock.

In fact, the whole structure of stack locking is sigprof is somewhat
wrong because it assumes the G to lock is gp.m.curg, but all three
gentraceback calls start from potentially different Gs.

To fix this, we lower the gcTryLockStackBarriers calls much closer to
the gentraceback calls. There are now three separate trylock calls,
each clearly associated with a gentraceback and the locked G clearly
matches the G from which the gentraceback starts. This actually brings
the sigprof logic closer to what it originally was before stack
barrier locking.

This depends on "runtime: increase assumed stack size in
externalthreadhandler" because it very slightly increases the stack
used by sigprof; without this other commit, this is enough to blow the
profiler thread's assumed stack size.

Fixes #12528 (hopefully for real this time!).

For the 1.5 branch, though it will require some backporting. On the
1.5 branch, this will *not* require the "runtime: increase assumed
stack size in externalthreadhandler" commit: there's no pcvalue cache,
so the used stack is smaller.

On Windows, externalthreadhandler currently sets the assumed stack
size for the profiler thread and the ctrlhandler threads to 8KB. The
actual stack size is determined by the SizeOfStackReserve field in the
binary set by the linker, which is currently at least 64KB (and
typically 128KB).

It turns out the profiler thread is running within a few words of the
8KB-(stack guard) bound set by externalthreadhandler. If it overflows
this bound, morestack crashes unceremoniously with an access
violation, which we then fail to handle, causing the whole process to
exit without explanation.

To avoid this problem and give us some breathing room, increase the
assumed stack size in externalthreadhandler to 32KB (there's some
unknown amount of stack already in use, so it's not safe to increase
this all the way to the reserve size).

We also document the relationships between externalthreadhandler and
SizeOfStackReserve to make this more obvious in the future.

If a sigprof happens during a cgo call, we traceback from the entry
point of the cgo call. However, if the SP is outside of the G's stack,
we'll then ignore this traceback, even if it was successful, and
overwrite it with just _ExternalCode.

Fix this by accepting any successful traceback, regardless of whether
we got it from a cgo entry point or from regular Go code.
