mheap_.heap_live is an atomically accessed uint64. It is currently not 8-byte
aligned on 32-bit platforms, which has been okay because it's only accessed via
Xadd64, which doesn't require alignment on 386 or ARM32. However, Xadd64 on
MIPS32 does require 8-byte alignment.
Add a padding field to force 8-byte alignment of heap_live and prevent an
alignment check crash on MIPS32.

From the doc comment:
Context returns the context for the current test or benchmark.
The context is cancelled when the test or benchmark finishes.
A goroutine started during a test or benchmark can wait for the
context's Done channel to become readable as a signal that the
test or benchmark is over, so that the goroutine can exit.

- Added support for If-Match and If-Unmodified-Since.
- Precondition checks now more strictly follow RFC 7232 section 6, which
affects precedence when multiple condition headers are present.
- When serving a 304, Last-Modified header is now removed when no ETag is
present (as suggested by RFC 7232 section 4.1).
- If-None-Match supports multiple ETags.
- ETag comparison now correctly handles weak ETags.

Consider a switch like
switch x {
case foo:
f()
g()
}
Before, the coverage annotation for the block calling f and g included
in its position span the text for 'case foo:'. This looks nice in the coverage
report, but it breaks the invariant that coverage blocks are disjoint if
you have a more complex expression like:
switch x {
case func() int { return foo }():
f()
g()
}
Then the coverage analysis wants to annotate the func literal body,
which overlaps with the case body, because the case body is considered
to begin at the case token.
Change the annotation for a case body to start just after the colon of
the case clause, avoiding any potential conflict with complex case
expressions. Could have started at the colon instead, but it seemed
less weird to start just after it.
Fixes#16540.
