riscv64: simplify assembly constructs not supported by tcc.

At the moment tcc does not support assembler instructions
with C expression operands. As a workaround read values
directly from stack.

lib/tests: 50-compare-rotated-weird.c: Add test for RV reloc

We detected the value in off64 in the test is not -1 as it should but 56
ones. This is because the rotation is applied as unsigned even with the
signed cast. This breaks many things in tcc.
* lib/tests/scaffold/50-compare-rotated-weird.c: New file.

lib: Support uppercase hex conversions.
...
Uppercase hex number conversions fail for abtol, strtol, strtoul,
strtoull, atoi, and abtod.
The following patch fixes it. This allows tcc to handle assembly
language, which is necessary to build the Fiwix kernel as part of the
kernel bootstrapping in progress for the live-bootstrap project.
* lib/ctype/isxdigit.c (isxdigit): Also allow A-F.
* lib/mes/abtol.c (abtol): Also cater for A-F.
