034a264a99 It turns out that the two dimensional vectors were causing big slowdowns 
in this for programs with lots of types (like the testcase in PR224).
The problem was that the type ID that the outer vector was using was not
very dense (as many types are getting resolved), so the vector is large
and gets reallocated a lot.

Since there are a lot of values in the program (the .ll file is 10M),
each reallocation has to copy the subvectors, which is also quite slow
(this wouldn't be a problem if C++ supported move semantics, but it
doesn't, at least not yet :(

Changing the outer data structure to a map speeds a release build of
llvm-as up from 11.21s to 5.13s on the testcase in PR224.

7eb118e4f7 When resolving upreferences, if multiple uprefs will be resolved to the same 
type at the same time, resolve the upreferences to each other before resolving
it to the outer type.  This shaves off some time from the testcase in PR224, from
25.41s -> 21.72s.

76292e7fcc Instead of searching the entire type graph for a type to determine if it 
contains the type we are looking for, just search the immediately used types.
We can only do this because we keep the "current" type in the nesting level
as we decrement upreferences.

This change speeds up the testcase in PR224 from 50.4s to 22.08s, not
too shabby.

645f8fb4e5 Upreferences are always OpaqueTypes, meaning that it is impossible for a non-abstract 
type from containing one.  This speeds up the asmparser on the testcase in PR224 from
61->50s.

allow 'except' instead of 'unwind' here though.

9a709fd181 Accept double quoted strings everwhere we accept a %ABC variable name. 
This introduces one more innoculous shift-reduce conflict, but will REALLY
help the type names generated by the C++ frontend, which wants to use all
kinds of crazy stuff.
