Add load/store functionality Summary: This patches allows non conversions like i1=i2; where both are global ints. In addition, arithmetic and other things start to work since fast-isel will use existing patterns for non fast-isel from tablegen files where applicable. In addition i8, i16 will work in this limited context for assignment without the need for sign extension (zero or signed). It does not matter how i8 or i16 are loaded (zero or sign extended) since only the 8 or 16 relevant bits are used and clang will ask for sign extension before using them in arithmetic. This is all made more complete in forthcoming patches. for example: int i, j=1, k=3; void foo() { i = j + k; } Keep in mind that this pass is not enabled right now and is an experimental pass It can only be enabled with a hidden option to llvm of -mips-fast-isel. Test Plan: Run test-suite, loadstore2.ll and I will run some executable tests.

Change the fast-isel-abort option from bool to int to enable "levels" Summary: Currently fast-isel-abort will only abort for regular instructions, and just warn for function calls, terminators, function arguments. There is already fast-isel-abort-args but nothing for calls and terminators. This change turns the fast-isel-abort options into an integer option, so that multiple levels of strictness can be defined. This will help no being surprised when the "abort" option indeed does not abort, and enables the possibility to write test that verifies that no intrinsics are forgotten by fast-isel.

Add mips32 r1 to the list of supported targets for Mips fast-isel Summary: Expand list of supported targets for Mips to include mips32 r1. Previously it only include r2. More patches are coming where there is a difference but in the current patches as pushed upstream, r1 and r2 are equivalent.
