For historic reasons, the behavior of .align differs between targets.
Fortunately, there are alternatives, .p2align and .balign, which make the
interpretation of the parameter explicit, and which behave consistently across
targets.
This patch teaches MC to use .p2align instead of .align, so that people reading
code for multiple architectures don't have to remember which way each platform
does its .align directive.

| How to organize the lit tests |
+==============================================================================+
- If you write a test for matching a single DAG opcode or intrinsic, it should
go in a file called {opcode_name,intrinsic_name}.ll (e.g. fadd.ll)
- If you write a test that matches several DAG opcodes and checks for a single
ISA instruction, then that test should go in a file called {ISA_name}.ll (e.g.
bfi_int.ll
- For all other tests, use your best judgement for organizing tests and naming
the files.
+==============================================================================+
| Naming conventions |
+==============================================================================+
- Use dash '-' and not underscore '_' to separate words in file names, unless
the file is named after a DAG opcode or ISA instruction that has an
underscore '_' in its name.
