An advantage is that there are less portability concerns when writing
tests. For example, `-u` is not supported by all implementations of
`env`, but lit's internal shell provides its own `env` that supports
`-u`.
A disadvantage is that some shell constructs, such as parentheses, are
not supported, but FileCheck's test suite currently doesn't require
such constructs.
For comparison, lit configures its test suite in the same manner. See
`llvm/utils/lit/tests/lit.cfg`.

`FILECHECK_OPTS` into environment for FileCheck tests.
Summary:
This fixes the following FileCheck tests:
* FileCheck/dump-input-enable.txt
* FileCheck/match-full-lines.txt
when `FILECHECK_DUMP_INPUT_ON_FAILURE` is set in the environment.
By default llvm-lit propagates `FILECHECK_DUMP_INPUT_ON_FAILURE` and
`FILECHECK_OPTS` from llvm-lit's environment into the test environment.
Unfortunately this can break FileCheck's tests because they expect that
these environment variables not to be set.

- Instead of setting the suffixes in a bunch of places, just set one master
list in the top-level config. We now only modify the suffix list in a few
suites that have one particular unique suffix (.ml, .mc, .yaml, .td, .py).
- Aside from removing the need for a bunch of lit.local.cfg files, this enables
4 tests that were inadvertently being skipped (one in
Transforms/BranchFolding, a .s file each in DebugInfo/AArch64 and
CodeGen/PowerPC, and one in CodeGen/SI which is now failing and has been
XFAILED).
- This commit also fixes a bunch of config files to use config.root instead of
older copy-pasted code.
