George Rimar ce6080819c [ELF] - Remove ScriptLexer::Error field and check ErrorCount instead.
D35945 introduces change when there is useless to check Error flag
in few places, but ErrorCount must be checked instead.

But then we probably can just check ErrorCount always. That should simplify
things. Patch do that.

Rui Ueyama f5fce48679 Handle ":" as a regular token character in linker scripts.
This is an alternative to https://reviews.llvm.org/D30500 to simplify the
version definition parser and allow ":" in symbol names.

Rui Ueyama 731a66ae98 Apply different tokenization rules to linker script expressions.
The linker script lexer is context-sensitive. In the regular context,
arithmetic operator characters are regular characters, but in the
expression context, they are independent tokens. This afects how the
lexer tokenizes "3*4", for example. (This kind of expression is real;
the Linux kernel uses it.)

This patch defines function `maybeSplitExpr`. This function splits the
current token into multiple expression tokens if the lexer is in the
expression context.

Rui Ueyama 794366a237 Rename ScriptParser.{cpp,h} -> ScriptLexer.{cpp,h}.
These files contain a lexer, so the new names are better.
The parser is in LinkerScript.{cpp,h}.
