Title: 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
