[arm] Implement eabi_attribute, cpu, and fpu directives. This commit allows the ARM integrated assembler to parse and assemble the code with .eabi_attribute, .cpu, and .fpu directives. To implement the feature, this commit moves the code from AttrEmitter to ARMTargetStreamers, and several new test cases related to cortex-m4, cortex-r5, and cortex-a15 are added. Besides, this commit also change the Subtarget->isFPOnlySP() to Subtarget->hasD16() to match the usage of .fpu directive. This commit changes the test cases: * Several .eabi_attribute directives in 2010-09-29-mc-asm-header-test.ll are removed because the .fpu directive already cover the functionality. * In the Cortex-A15 test case, the value for Tag_Advanced_SIMD_arch has be changed from 1 to 2, which is more precise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193524 91177308-0d34-0410-b5e6-96231b3b80d8

Stop uppercasing build attribute data. The string data for string-valued build attributes were being unconditionally uppercased. There is no mention in the ARM ABI addenda about case conventions, so it's technically implementation defined as to whether the data are capitialised in some way or not. However, there are good reasons not to captialise the data. * It's less work. * Some vendors may legitimately have case-sensitive checks for these attributes which would fail on LLVM generated object files. * There could be locale issues with uppercasing. The original reasons for uppercasing appear to have stemmed from an old codesourcery toolchain behaviour, see http://comments.gmane.org/gmane.comp.compilers.llvm.cvs/87133 This patch makes the object file emitted no longer captialise string data, it encodes as seen in the assembly source.
