This feature is not yet ready for real use. The CL marks a bite-sized
piece that is ready for review. TODOs that remain:
provide control over output
produce output without setting -v
make work on reflect, sync and time packages
(fail now due to link errors caused by inlining)
better documentation
Almost all packages work now, though, if clumsily; try:
go test -v -cover=count encoding/binary

Requires adding new linker instruction
RET f(SB)
meaning return but then immediately call f.
This is what you'd use to implement a tail call after
fiddling with the arguments, but the compiler only
uses it in genwrapper.
This CL eliminates the copy-and-paste genembedtramp
functions from 5g/8g/6g and makes the code run on ARM
for the first time. It removes a small special case for function
generation, which should help Carl a bit, but at the same time
it does not bother to implement general tail call optimization,
which we do not want anyway.
Fixes#5627.

The first identifier in an Object Identifer must be between 0 and 2
inclusive. The range of values that the second one can take depends
on the value of the first one.
The two first identifiers are not necessarily encoded in a single octet,
but in a varint.

The new code matches the code in cc/lex.c and the #define GETC.
This was causing problems scanning runtime·foo if the leading
· byte was returned by the buffer fill.

Do not synchronize Add(1) with Wait().
Imitate read on first Add(1) and write on Wait(),
it allows to catch common misuses of WaitGroup:
- Add() called in the additional goroutine itself
- incorrect reuse of WaitGroup with multiple waiters

Also reduce FixAlloc allocation granulatiry from 128k to 16k,
small programs do not need that much memory for MCache's and MSpan's.

Especially important for Windows because it reserves VM
only in multiple of 64k.

Count only number of frees, everything else is derivable

CFLAGS comes before CPPFLAGS.
Also fix one typo CPPCFLAGS.
Cleanup for CL 8248043.

It was never tested and also breaks Windows.
run.go doesn't yet support the proper !windows,!plan9 syntax.

The significant change between TLS 1.0 and 1.1 is the addition of an explicit IV in the case of CBC encrypted records. Support for TLS 1.1 is needed in order to support TLS 1.2.
