For expressions containing a TypeSwitchGuard with a short variable
declaration e.g. var := x.(type), the spec says that var is declared
at the beginning of the implicit block for each in each clause.
Previously, var was declared in the block for the switch statement
and each implicit block, which led to errors if the type case clause
referenced a type with a similar name as the declared variable.
Fixesgolang/go#10047.

Fix PR65261
Running bootstrap-ubsan on ppc64le shows many instances of:
libcpp/lex.c:552:30: runtime error: load of misaligned address
0x01001f31d37a for type 'const uchar', which requires 16 byte alignment
But the unaligned vector loads are intended in this case, because they
are preferable to forced-alignment on POWER8. So just silence the ubsan
errors.
