Log Message:
lint: clean up

In symtab_search, most of the conditions were redundant, so remove them.

In read_byte, using CHAR_MASK was conceptually wrong, as that constant
is from the target platform while the lexical analysis happens on the
host platform.  It was unnecessary as well, as a hypothetical host
platform with 36-bit chars might encode the characters from the basic
source character set as numbers higher than 0x0_0000_00ff.  Since lint
assumes that both the source character set as well as the execution
character set are the same and based on 8-bit bytes, nothing changes.

No functional change.
