bec7b766fb rustc: Move to FNV hashing for node/def ids 
This leverages the new hashing framework and hashmap implementation to provide a
much speedier hashing algorithm for node ids and def ids. The hash algorithm
used is currentl FNV hashing, but it's quite easy to swap out.

I originally implemented hashing as the identity function, but this actually
ended up in slowing down rustc compiling libstd from 8s to 13s. I would suspect
that this is a result of a large number of collisions.

With FNV hashing, we get these timings (compiling with --no-trans, in seconds):

|           |  before  |  after  |
|-----------|---------:|--------:|
| libstd    |   8.324  |  6.703  |
| stdtest   |  47.674  | 46.857  |
| libsyntax |   9.918  |  8.400  |

2a14e084cf Move std::{trie, hashmap} to libcollections 
These two containers are indeed collections, so their place is in
libcollections, not in libstd. There will always be a hash map as part of the
standard distribution of Rust, but by moving it out of the standard library it
makes libstd that much more portable to more platforms and environments.

This conveniently also removes the stuttering of 'std::hashmap::HashMap',
although 'collections::HashMap' is only one character shorter.

071ee96277 Consolidate codegen-related compiler flags 
Move them all behind a new -C switch. This migrates some -Z flags and some
top-level flags behind this -C codegen option.

The -C flag takes values of the form "-C name=value" where the "=value" is
optional for some flags.

Flags affected:

* --llvm-args           => -C llvm-args
* --passes              => -C passes
* --ar                  => -C ar
* --linker              => -C linker
* --link-args           => -C link-args
* --target-cpu          => -C target-cpu
* --target-feature      => -C target-fature
* --android-cross-path  => -C android-cross-path
* --save-temps          => -C save-temps
* --no-rpath            => -C no-rpath
* -Z no-prepopulate     => -C no-prepopulate-passes
* -Z no-vectorize-loops => -C no-vectorize-loops
* -Z no-vectorize-slp   => -C no-vectorize-slp
* -Z soft-float         => -C soft-float
* -Z gen-crate-map      => -C gen-crate-map
* -Z prefer-dynamic     => -C prefer-dynamic
* -Z no-integrated-as   => -C no-integrated-as

As a bonus, this also promotes the -Z extra-debug-info flag to a first class -g
or --debuginfo flag.

* -Z debug-info         => removed
* -Z extra-debug-info   => -g or --debuginfo

Closes #9770
Closes #12000

eced501226 allow generating drop glue without the TyDesc 
Reflection is now the only user of type descriptors. Uses of drop glue
no longer cause a type descriptor to be generated.
