879a1ff1e4 test: improve asmcheck syntax
asmcheck comments now support a compact form of specifying
multiple checks for each platform, using the following syntax:

   amd64:"SHL\t[$]4","SHR\t[$]4"

Negative checks are also parsed using the following syntax:

   amd64:-"ROR"

though they are still not working.

Moreover, out-of-line comments have been implemented. This
allows to specify asmchecks on comment-only lines, that will
be matched on the first subsequent non-comment non-empty line.

    // amd64:"XOR"
    // arm:"EOR"

    x ^= 1

c9438cb198 test: add support for code generation tests (asmcheck)
The top-level test harness is modified to support a new kind
of test: "asmcheck". This is meant to replace asm_test.go
as an easier and more readable way to test code generation.

I've added a couple of codegen tests to get initial feedback
on the syntax. I've created them under a common "codegen"
subdirectory, so that it's easier to run them all with
"go run run.go -v codegen".

The asmcheck syntax allows to insert line comments that
can specify a regular expression to match in the assembly code,
for multiple architectures (the testsuite will automatically
build each testfile multiple times, one per mentioned architecture).

Negative matches are unsupported for now, so this cannot fully
replace asm_test yet.
