Re-commit: [mips] Correct section alignments and EntrySizes for .bss, .text, .data, .reginfo, .MIPS.options, and .MIPS.abiflags
...
The lld tests will temporarily fail again but Simon Atanasyan will commit a fix for those shortly.

This commit causes multiple lld tests to fail. Reverting while I investigate the issue.

[mips] Correct section alignments and EntrySizes for .bss, .text, .data, .reginfo, .MIPS.options, and .MIPS.abiflags
...
Summary:
.bss, .text, and .data are at least 16-byte aligned.
.reginfo is 4-byte aligned and has a 24-byte EntrySize.
.MIPS.abiflags has an 24-byte EntrySize.
.MIPS.options is 8-byte aligned and has 1-byte EntrySize.
Using a 1-byte EntrySize for .MIPS.options seems strange because the
records are neither 1-byte long nor fixed-length but this matches the value
that GAS emits.

Mips.abiflags is a new implicitly generated section that will be present on all new modules. The section contains a versioned data structure which represents essentially information to allow a program loader to determine the requirements of the application. This patch implements mips.abiflags section and provides test cases for it.
