Max Neverov 665af86992 cmd/go: fail go clean command when failed to find go cache directory
Currently, if computing of the go cache directory fails it does not expose the error. Commands like go clean, exec, modindex that use go cache directory continue execution producing incorrect or no result. This patch adds an error to the return values such that it can be validated on call sites. It also introduces such validation in go clean -cache command to fail execution in case when error occurred.

Fixes #69997

Mateusz Poliwczak 19b6f01161 go/parser: add *ast.BlockStmt depth test
At first glance i have thought that we do not handle such case properly,
because parseBlockStmt and parseStmtList do not call call the
incNestLev. Fortunately parseStmt does, so it is detected properly.

As we don't have a test case directly for blockstmts only, i think it is
worth adding one.

Mark Ryan 1aee4f3464 cmd/internal/obj/riscv: prevent panics on bad branches
Syntactically incorrect branches, such as

BEQ	X5, X6, $1
BEQ	X5, X6, 31(X10)

cause the assembler to panic, which they shouldn't really do.  It's
better for the user to see a normal error, as reported for other
syntax errors in riscv64 assembly.  The panics also prevent us
from writing negative tests for these sorts of errors.

Here we fix the issue by ensuring we generate a normal error instead
of panicking when the user provides an invalid branch target.  We
also add a couple of negative tests.

Mark Ryan 24b395119b cmd/internal/obj/riscv: prevent duplicate error reports
The riscv64 Go assembler can output certain errors, ones produced by
instructionsForProg, multiple times.  These errors are guaranteed to
be output at least twice and can appear three or more times if a
rescan is needed to recompute branch addresses.  For example, the
syntactically incorrect instruction

MOV	(X10), $1

will generate at least two identical errors

asm: 86076 (asm.s:21524)	MOV	(X10), $1: unsupported MOV
asm: 86076 (asm.s:21524)	MOV	(X10), $1: unsupported MOV
asm: assembly failed

In addition to confusing the user, these duplicate errors make it
difficult to write negative tests for certain types of instructions,
e.g., branches, whose duplicate errors are not always identical,
and so not ignored by endtoend_test.go.

We fix the issue by returning from preprocess if any errors have been
generated by the time we reach the end of the rescan loop. One
implication of this change is that validation errors will no longer
be reported if an error is generated earlier in the preprocess stage.
Negative test cases for validation errors are therefore moved to
their own file as the existing riscv64error.s file contains errors
generated by instructionsForProg that will now suppress the
validation errors.
