[WebAssembly] Convert the remaining unit tests to the new wasm-object-file target. To facilitate this, add a new hidden command-line option to disable the explicit-locals pass. That causes llc to emit invalid code that doesn't have all locals converted to get_local/set_local, however it simplifies testwriting in many cases. llvm-svn: 296540

WebAssembly: handle private/internal globals. Things of note: - Other linkage types aren't handled yet. We'll figure it out with dynamic linking. - Special LLVM globals are either ignored, or error out for now. - TLS isn't supported yet (WebAssembly will have threads later). - There currently isn't a syntax for alignment, I left it in a comment so it's easy to hook up. - Undef is convereted to whatever the type's appropriate null value is. - assert versus report_fatal_error: follow what other AsmPrinters do, and assert only on what should have been caught elsewhere. llvm-svn: 246092

[WebAssembly] Fix printing of global operands This was regressed in r252656 which wasn't quite NFC. Instead of using a custom instruction as before, use a pattern to select CONST_I32 for the global addrs. Differential Revision: http://reviews.llvm.org/D14587 llvm-svn: 253276

[WebAssembly] Implement instruction selection for constant offsets in addresses. Add instruction patterns for matching load and store instructions with constant offsets in addresses. The code is fairly redundant due to the need to replicate everything between imm, tglobaldadr, and texternalsym, but this appears to be common tablegen practice. The main alternative appears to be to introduce matching functions with C++ code, but sticking with purely generated matchers seems better for now. Also note that this doesn't yet support offsets from getelementptr, which will be the most common case; that will depend on a change in target-independent code in order to set the NoUnsignedWrap flag, which I'll submit separately. Until then, the testcase uses ptrtoint+add+inttoptr with a nuw on the add. Also implement isLegalAddressingMode with an approximation of this.

It also uses conventional data section directives like ".byte" and so on rather than requiring everything to be in hierarchical S-expression format.

[MC] Use .p2align instead of .align 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.
