This makes LexCharConstant() look more like LexStringLiteral(), which doesn't
have this bug. Add tests for eof after \ for several other cases.

common LexStringLiteral function.  In doing so, some consistency problems have
been ironed out (e.g. where the first token in the string literal was lexed
with macro expansion, but subsequent ones were not) and also an erroneous
diagnostic has been corrected.

LexStringLiteral is complemented by a FinishLexStringLiteral function which
can be used in the situation where the first token of the string literal has
already been lexed.

Add a new function to ConstantExpr - getAsInstruction. This returns its Instruction* corollary, which may be useful if a user
wishes to transform a ConstantExpr so that one of its operands is no longer constant.

It's also simpler to just copy the words than mangling bits like this ctor did.

This is a partial solution to PR14351. It removes some of the special
significance of the first incoming phi value in the phi aliasing checking logic
in BasicAA. In the context of a loop, the old logic assumes that the first
incoming value is the interesting one (meaning that it is the one that comes
from outside the loop), but this is often not the case.  With this change, we
now test first the incoming value that comes from a block other than the parent
of the phi being tested.

This provides a 3.5% reduction in -fsyntax-only time on sqlite3.c.
